One out of 14 Catholic priests is -- not a just pedophile, just a molester, but a serial-molester?! This is such an unlikely mathematical distribution (especially spread over a giant sample of tens of thousands of priests nationwide) that serial-molesters must be deliberately targeting the job; not developing from inside the priesthood out.
Since I began spamming the "eighth-grade math" insight above to Catholic addresses all over the country, I actually began researching the problem a little (began reading the 2002 book, Goodbye! Good Men). Seems the heart of the problem may be that we are force feeding likely predators down seminary throats (reminds of live geese being force fed grain to prepare for cooking).
What I read doesn't reassure me that even fair psychological testing is up to winnowing out these guys -- anything but. Prejudiced (by Catholic standards) testing being (SUPER) UN-sophisticated enough to find orthodox believing Catholic men to be the sexually maladjusted signals a lack of a sufficiently worked out "science."
Here as in another science that is not worked out, economics, higher intelligence and heavier common sense may be more of a help than so-called higher theoretical training -- why psychiatrists often make better therapists than psychologists.
Since adherence to unorthodox (to us) religious concepts seem to be opening the flood gates here, the first logical remedy may be to institute just the opposite in all vocation screening (using only devout Catholic shrinks? -- sounds like a very good idea).
I would have been one to accept homosexual men into the priesthood (as long as they are celibate of course). But after reading as far as partying type homosexuals seemingly hijacking the Jesuits, at least in California -- DEFINITELY targeting; if not necessarily for molesting -- and seemingly in many other milieus across the country, I begin to think that barring homosexuals as a general rule may be the only way to take this segment of the priesthood back to the church (perhaps making exception for the exceptionally devout -- I am sure there are may of them in the closet).
The Jesuit seminary abuse stories put a caveat in my "too unlikely" 1 in 14 theory. Males in positions of power in any venue have a serious probability of taking advantage of underlings. The seminary stories gave me this idea -- but it could apply to adults in charge of children too.
If bishops are not sufficiently interested in closing off the (if I am right) still wide open molester pipeline for the sake of protecting children -- perhaps they should consider cleaning things out before they are forced to auction off St. Patrick's Cathedral.
Last thing for now: if dioceses that prohibit altar girls have a big drop in vocations -- and this does not simply coincide with their being unorthodox overall -- and the reason for the drop may be because fewer boys are exposed to the altar, it is possible to include more boys while keeping the girls at the same number while explaining the reason. At this stage in our civilization it is almost a scandal (in the relative sense) to prohibit girls.
So much for today; I'll probably spend a month before I come up with another good spam.

The way I see it, these photos, taken just 5 months before she passed away, were a hint of what we would have seen next in Diana's life: a happier, independent and grown up woman who was finally free from the life that so rigidly defined her. It's as if in the photos from the decade before she was playing a role, and in these pictures she is finally able to just be herself. She never looked more beautiful.

I agree that there are no African Americans because the dark complexion indigenous people did not orginate in Africa, they are of near Asian orgin. There are many ancient Hebrew artifacts that have discovered in the Americans. These artifacts have been covered up by atheist and Ashkenazi Jews which have assumed the identity of the decendants of Abraham. The first European settlers all believed that the indigenous tribes were Hebrews. Even the tribes called the old testament a transcript of their culture. Perhaps the Moorish people came with the Europeans from the Iberia? I'm am not a Hebrew Israelite by faith that believes that all the slaves came from negroland in West Africa because I know that the cast majority of slaves were indigenous peoples.

However I have read many accounts that lead to the conclusion that at least some of the indigenous people were of Hebrew orgin. Even the Ashkenazis admit this fact and have places it in many of their Hollywood productions. I once had a Ashkenazi rabbi tell me that I could be a Hebrew. That was 30 years ago but has time has moved on I realize he was trying to tell me something with out getting in trouble for spilling the beans. He was begging me to do my own research. I can't tell you the truth but I encourage you to dig for yourself that was his scripted message to me.

Carp muster will feature in this year's Gone Fishing day
Remember last year's Gone Fishing day at Tenterfield Dam? Lots of fun was had but conditions were atrocious, and organisers are hoping to avoid a repeat with a rescheduling of this year's event to this Sunday, October 28.
There's also been a relocation downstream to Tenterfield Creek, where the statewide Gone Fishing Day becomes a Carp Muster in Tenterfield, with the noxious pest in the sights of fishers old and new.
Organiser Michael Davey of OzFish said the stretch of creek from behind Coles to Naas Street is badly affected by trench carp.
These invaders eat the eggs of native species like the threatened catfish and murray cod.
They also tend to stir up the mud which absorbs oxygen, affecting water quality and making it difficult for other creek life to breath.
Participants will be equipped to tempt carp onto the hooks over native breeds, with a variety of soft plastic lures and a carp delicacy: corn kernels. Mr Davey said there'll be a few fishing with worms and at least one with his fly rod.
"Carp love taking flies off the surface."
The carp muster follows a workshop in Shirley Park conducted by NSW Fisheries looking at fishing rigs, safe fish handling, size and bag limits and how to cast a line.
The new OzFish tent bought through a $500 Tenterfield Shire Council community grant will get an airing, so look for it at the park.
So far 32 have signed up for the one-hour workshop (from 10am) and only four spots remain, so go to the Tenterfield OzFish Unlimited Facebook page or call Mr Davey on 0412 241 934 if you're interested.
The action then moves to the creek with everyone invited to take part in the muster by throwing in a line somewhere between Shirley Park and Naas Street, although parental supervision is required for younger fishers.
All participants go into the draw for new rods and there are more prizes for those putting a dint in the carp population. OzFish will have a sausage sizzle with the snags again donated by Wizards Butchery.
Mr Davey hopes to educate local kids on creek health in the hope that they may opt to come done after school and do a bit of fishing, so the carp population is controlled if not eliminated.
He said there are probably a dozen carp in the creek below the Bowling Club, and more in the pools near Millrace.
Discuss "Carp muster will feature in this year's Gone Fishing day"

Jack Swarbrick Press Conference Transcript | Notre Dame Schedule Notes | 2014 Schedule | 2015 Schedule | 2016 Schedule
The University of Notre Dame today announced its football schedules for 2014, 2015 and 2016 – the first three years of its new football relationship with the Atlantic Coast Conference.
Those three seasons are the initial ones in which the Irish play five games per year against ACC opponents, with Notre Dame also in 2014 beginning its affiliation in the ACC postseason bowl alignment.
A slight variation in the first two seasons will have Notre Dame playing four ACC foes in 2014, then six in 2015.
Those next three seasons, combined with the 2012 and 2013 schedules, show the Irish playing games in 10 of the top 12 metropolitan television markets in the country – New York (two games), Los Angeles (three), Chicago, Philadelphia, Dallas-Fort Worth, San Francisco-Oakland-San Jose (two), Boston, Washington, D.C., Detroit and Phoenix. Notre Dame also played in Dublin, Ireland, in 2012.
In addition, those five years include 29 combined regular-season games against 13 different teams that ranked in the Bowl Championship Series poll at some point in 2013 – five each versus Stanford and USC, three versus Michigan and Michigan State, two each versus Oklahoma, Texas, Miami and Arizona State, plus one each versus Florida State, Clemson, Duke, Virginia Tech and Louisville.
"Our schedules the next three seasons, combined with our 2012 and 2013 schedules, truly exhibit Notre Dame's intention to celebrate our independence," says Notre Dame vice president and director of athletics Jack Swarbrick.
"We will be playing in virtually every corner of the country and will have a strength of schedule that will serve us well in the new College Football Playoff format."
The Irish will play their annual Shamrock Series games in 2014 in Indianapolis (Lucas Oil Stadium) against Purdue, in 2015 in Boston (Fenway Park) against Boston College and in 2016 in San Antonio (Alamodome) against Army. All three of those games will be televised in prime time by NBC.
ACC programs headed to Notre Dame Stadium include North Carolina and Louisville in 2014; Wake Forest and Georgia Tech in 2015, and then Duke, Miami and Virginia Tech in 2016.
The Irish normally will play an alternating list of ACC opponents – with three games at home and two on the road one year, followed by three on the road and two at home the next season.
Notre Dame's game against Virginia Tech in 2016 will mark the first time those two programs have met – and the 2016 Irish matchup at North Carolina State will qualify as the first regular-season meeting between those two programs (their only previous matchup was in the Gator Bowl after the 2002 season). Notre Dame's visit to Charlottesville, Va., to play Virginia in 2015 will mark its first (the only previous meeting between those teams came in Giants Stadium in the 1989 Kickoff Classic).
Future Irish road schedules send Notre Dame to play away from home against two 2013 final BSC top-12 opponents – at Florida State (final BCS #1) in 2014 in Tallahassee, Fla., and at Clemson (BCS #12) in 2015 in Clemson, S.C.
In addition, in 2015 the Irish begin a four-game series with traditional power Texas – with the first game set for the 2015 Notre Dame season opener in Notre Dame Stadium and the second as the 2016 Irish season opener in Austin.
Notre Dame also will play host to Northwestern in 2014 at Notre Dame Stadium, in the Wildcats' first visit to South Bend since 1995.
The Irish in both 2014 and 2016 will play ACC foe Syracuse at MetLife Stadium in East Rutherford, N.J.
The 2014 Irish home game against Michigan will be a night game and will be televised in prime time by NBC.

Elder Patriot – While the mainstream media spent the past decade-plus ignoring this story and alibying for high-profile friends of accused pedophile, Jeffrey Epstein, the Miami Herald has been doggedly pursuing evidence and victims of the politically connected billionaire.
Among those connected to Epstein, and his infamous Pedophile Island, is former President Bill Clinton whose name is said to appear twenty-seven times on flight logs for Epstein's private jet, dubbed the Lolita Express.
Investigative reporter Conchita Sarnoff told Fox News" Shannon Bream that almost every time Clinton was on the plane there were underage girls on the plane. Make what you will of this information.
(Miami Herald) At least a dozen new victims have come forward to claim they were sexually abused by Jeffrey Epstein…
The Miami Herald article continues:
Following Epstein's arrest Saturday in New Jersey, four women have reached out to New York lawyer David Boies, and at least 10 other women have approached other lawyers who have represented dozens of Epstein's alleged victims in the past.
Jack Scarola, a Palm Beach attorney, said at least five women, all of whom were minors at the time of their alleged encounters with Epstein, have reached out to either him or Fort Lauderdale lawyer Brad Edwards.
"The people we are speaking to are underage victims in Florida and in New York. They are not individuals whose claims have previously been part of any law enforcement investigation," Scarola said.
According to the report in the Herald, prosecutors claim to have information that Epstein recruited and paid dozens of underage girls for sex in New York and Florida.
While it's a virtual certainty that Epstein is guilty, probably on all counts, the real question is whether U.S. attorneys from the SDNY have the stomach for prosecuting cases against Epstein's high-profile friends.
There's got to be a reason so many of the so-called "elites" sought out Epstein's companionship and then continued to protect him.
The accused pedophile has spent decades being photographed with former and future presidents, wealthy icons of business, academicians, and celebrities.
Because of his wealth and his contacts across the globe, and the potential that he may be sentenced to 45 years in prison, prosecutors consider Epstein a flight risk. They requested the court to remand Epstein without bail.
Victims' lawyers also told the court that, during the 2006-2007 Palm Beach investigation, Epstein's previously sought to intimidate victims and their families, and that therefore bail should be denied.
According to prior reporting by the Miami Herald federal agents considered charging Epstein with witness tampering because he used some of his employees to try to intimidate victims so that they wouldn't cooperate with police.
In one instance, a victim's father told Palm Beach police that he had been followed by someone and forced off the road. He wrote down the car's license plate number and police traced it to a private investigation company that had been hired by Epstein's legal team, the police report about the incident said.
Epstein's investigators also followed the then-Palm Beach police chief, Michael Reiter, and the lead detective in the case, Joe Recarey. Recarey said he was so concerned about the aggressive tactics Epstein was using that he would often switch vehicles in an attempt to throw them off.
"At some point it became like a cat-and-mouse game. I would stop at a red light and go. I knew they were there, and they knew I knew they were there. I was concerned about my kids because I didn't know if it was someone that they hired just out of prison that would hurt me or my family,'' Recarey told the Herald as part of its series on the case.
Recarey, who died shortly after he was interviewed by the Herald, said the victims, who were as young as 13, were scared to death of Epstein, and even more so because of the private investigators and defense lawyers who dug into every dark corner of their lives, and the lives of their brothers, sisters, parents and boyfriends.
Who are these connected, rich and powerful people that ordered prosecutors to ignore the clear obstruction of justice that was being carried out by Epstein's minions?
They wouldn't be the same players that seem so desperate to charge President Trump with obstruction of justice over a crime that wasn't, would they?

Record breaking NYD parkrun at Perry Hall
Over 500 participants got the New Year off to a flying start at the Perry Hall parkrun (Tuesday 1 January). The large turnout proved to be a challenge for the results team but they were more than up to the task.
Perry Hall had seen a record attendance of 223 runners on the 1 December, as the event celebrated its fourth birthday. That unexpected present made it an extra special day for everyone involved; however, that figure would be exceeded in dramatic fashion on the 1 January.
Every parkrun can choose to host an extra event on New Year's Day and Event Director Emma Hawkey and her core team opted to do so. There were a few logistical issues to consider namely that of runner numbers and after looking at previous years, a projection of 350 participants maximum was made.
The New Year's Day parkrun started at 10.30am and involved the completion of three laps on tarmac, grass and gravel paths around Perry Hall Park. It was busy day for the volunteer team as 561 runners crossed the line – double the projected attendance. The mammoth field saw Perry Hall proudly claim the biggest percentage increase in numbers out of 330 parkruns taking place on 1 January.
Feedback was overwhelmingly positive, praising the course, the runners and the volunteers as well as the incredible turnout. This small but mighty parkrun has a community feel and is best summed up by Run Director Phillip who said: "Perry Hall parkrun never fails to engage all, inspire and positively impact on those taking part."
The parkrun team thanked everyone for making the event a huge success with additional thanks going to the Friends of Perry Hall Accredited Country Park whose support has been invaluable.

"Now-a-days they can do surgery on your eyes, and no matter what age you are, you can have 20-20 vision. If you can't hear, they have a device that makes it so you can hear as good as you could the day you were born, but let me tell you people, you can't fix stupid."
-Ron White-
I have seen so much that fits that description lately that I can't help but think of that quote from Ron White. I mean, it fits. The American people, on November 2nd, in droves, told Pelosi, and Obama to stop the spending, and essentially repent, but what did they do? After getting the snot beat out of them in the election, they went into the Lame Duck session from hell, passing everything they could to force more crap on us the people, and more stuff to hurt this nation. Did they learn anything? You can fix idiocy, because it is based on not knowing something, but YOU CAN'T FIX STUPID folks! It's based on knowing but changing the truth so it fits your agenda. You can't fix stupid.
Obama is told by polls, and people sending messages to Washington that we do not want his health care program. He turns around and does everything he can to pass it, over our objections, like it didn't matter. Did he learn anything? YOU CAN'T FIX STUPID! The trouble is, Obama is not stupid. But even smart people, can be totally stupid. Obama, and the liberal left, is totally committed to ruining this nation. But to me, that is STUPID folks. Because we live in the greatest nation this world has ever seen. Why ruin it? YOU CAN'T FIX STUPID!
Don't these people know that if you go against the will of the people, there is an election coming up that will oust them?
Actually, I think they do know, but the problem lies in the power that they now have, along with their arrogance, and that they actually believe, what they are doing is for the best, and that we the people cannot survive without them and their so called leadership. They have NO COMMON SENSE!
They actually believe that the people voted them into office to do what they are doing.
They actually believe, that the polls are wrong and that the emails and mail they get are not telling them the things that they are to do. Which is why, this country cannot afford to keep them in office.
Now, Obama doesn't care if he is ousted from office, because, as a president, he now has an income granted to him for the rest of his life. One way and above anything he has ever had before. HE DOESN'T CARE. We gave him the life of opulence that he wanted, and that is our fault. If it was up to me, that clause in the constitution would be changed to this: Once you are president, you have your income for the rest of your life, after leaving office, IF you do a good job while president. Do you know how much money just that would save the American taxpayer? We would no longer be paying Clinton or Carter.
We have to wake up here people. The money that they, in Washington, are spending so freely? That money comes from us, the taxpayers. It's time we started thinking of that money as ours, and make them spend the way we have to. Thriftly and smartly. Cause if they don't, then they run out of money. The government is always in danger of "shutting down" if money isn't found to fund it. And they always get it because all they have to do is re-appropriate it from something else. We know we can't do that in our budgets like the government can. We have to cut spending, and try to save. Why can't the government do that? I can tell you why. Because we the people have allowed them to do this, like, forever. It is time we took the reins back and got the grassroots in politics going again. We need to get people in there who do not want politics for a career, and only want to do what is best for this country. That is the only way to fix stupid folks. Get rid of stupid, and things will get fixed, because spending would stop when we can't afford it.
And now, onto a brighter subject. Rep. Gabrielle Giffords, of Texas, the congresswoman who was shot in the head one week ago today, has made amazing progress, and is moving her arms and legs. Pointing at things when asked too, and has opened her eyes on her own.
Now folks, if this isn't an example of God working miracles in answer to millions of prayers, I don't know what is. Many of which, have come from my household, and I know, yours.. In my eyes, I have beheld a miracle of God's greatness, and His ability to help in our lives.
May God bless our efforts to help get America back, and put God back into our country.
God, Bless America. Bless Americans.

Special workshop "Legitimacy 2.0: Transparency Online", Belo Horizonte (Brazil)Wednesday, January 23rd, 2013
E-transparency is currently one the fastest-growing branches of transparency research. As Albert Meijer of the Open Government research group argues: "Modern day transparency is Internet transparency." The special workshop Legitimacy 2.0: Transparency Online allows participants to discuss this topic in the context of the philosophy of (social) rights.
The workshop is introduced as follows:
"Transparency is everywhere, or at least talk of it is everywhere. The mainstream view is that transparency furthers accountability and offers an antidote against corruption, both in the private and the public sector. It is not any specific right or principle, rather a feature of institutions embedded in the ideal of open society and often considered a requirement for efficiency and good governance. As essential to guarantee authority and effectiveness of rules, but also democratic participation, it is fundamental to assure obedience to the law and trust in institutions. Conversely, the lack of transparency might contribute to arbitrary power. Does the introduction of ICTs higher the quality of epistemic processes and outputs into the legal and political system? Does greater transparency of the network, e.g., through e-government tools, lead to increased participation, more active and responsible citizen involvement in decision-making, on local, national and supranational levels? What impact does web 2.0 technologies have? What could be the effects of information overload in the long run?

NI poets shortlisted for prize
Two Northern Irish poets have been shortlisted for one of the most prestigious prizes in poetry.
Michael Longley and Sinead Morrissey are both on the five-person shortlist for the Forward Prize for best poetry collection.
Longley has been shortlisted for his collection 'Angel Hill,' which explores the landscapes of Ireland and Scotland.
Morrissey - a former Belfast poet laureate - has been nominated for 'On Balance'.
Her collection includes poems about engineering feats like the Titanic, Lillian Bland's aeroplane and Marconi's radio.
The Irish poet Tara Bergin has also made the shortlist for her book 'The Tragic Death of Eleanor Marx.'
The journalist and broadcaster Andrew Marr chairs the prize's judging panel.
"I came away more than ever convinced than ever that if you read journalism alone, or history alone, and yet you omit contemporary poetry, then you cannot properly understand the world you live in," he said.
The Forward Prize winner will be announced at a ceremony at London's Royal Festival Hall in September.
The award is worth £10,000 and previous winners have included Seamus Heaney, Ted Hughes and Carol Ann Duffy.

Tractor sales are up. Tractor sales are down. Both of these statements are true, but how can that be? It's all in how you look at the numbers.
According to recent reporting by the Association of Equipment Manufacturers (AEM), tractor sales have definitely been a bit of a mixed bag. Four-wheel drive farm tractor sales are down 15% this year, and combine sales are down 17% this year. But other categories are showing modest gains, according to AEM ag sector lead Charlie O'Brien.
"Smaller horsepower tractors, under 40 horsepower, are up 8.7%, and horsepower at 40-100 are up 7%," he says, speculating that demand from the dairy sector could be partly fueling these increases.
AEM also looks at net farm income as it could relate to future equipment sales, explains AEM market intelligence analyst Benjamin Duyck.
"When we look at farm income business income, we can get a better sense where farm income is expected to increase and decrease," he says.
The areas hit hardest by reduced farm income include the Northern Great Plains (-14.8%), the Heartland (-16.4%) and the Mississippi portal (a/k/a the Mid-South, -27.5%). Duyck says the big question right now is how long the downturn in farm income will last. According to USDA analysis, a gentle decline in export values and farm cash receipts could continue through 2016, and increase after that.
And while lower commodity prices remain the driving force behind these changes, Duyck says other factors are also in play. First of all, he says capital expenditures on machinery are expected to decrease from past highs due to a change in tax incentives and subsidies. Second, farmland values are rising slowly enough that they can limit a farmer's ability to use it as collateral, thus reducing capacity to get credit. Third, Duyck says the used equipment market has become inflated in recent years.
"The large inventory of used equipment sitting on dealer lots is not only decreasing the ability of the dealers to purchase and finance new equipment, but is also lowering the value of the trade-ins farmers tend to use when buying new equipment," he says.
Duyck predicts farm equipment sales will experience a "multi-year adjustment" from historical highs. O'Brien adds that he is hopeful most farmers are still carrying strong balance sheets from prior years, and that the need for increased productivity and efficiency is ever-present.
"We continue to need the technology that our equipment offers," he says.

First turns of the winter! Shortly a week before the season starts in the Eastern Alps, in Norway it never ended.
Never ended? Watch the video!
Last Sunday Daniel Furberg and Terje Hoihjelle headed up to Sogndalsfjellet and Steindalsnosi for the first turns of the winter. The powder layer they found was very thin, but it was there!
Sogndal is a pretty good place to live - Daniel now has 13 consecutive months of snowboarding.
Big Thanks to Terje Valen Høihjelle for the impressive pictures.
Sogndal in western Norway is a lively small community of less than 8000 people and lies about 230km northeast of Bergen. By the way, the Sognefjord is the longest and deepest fjord in Europe.

SERENA WILLIAMS (USA) def. ELENA DEMENTIEVA (RUS) 6-2, 6-4
It was by the far the least dramatic of the three round-robin matches played on Thursday, with an extremely subdued Serena coming out on court with a new fashion accessory: a heavy, Caroline Wozniacki-style wrap on her upper left leg.
tap here to see other videos from our team.
Doha Day 3 - Serena vs. Dementieva Back to video
She also was having a serious "foundation garment" issue – not the fashionable girl we're used to seeing.
All of that certainly wasn't too promising.
Neither were the five double-faults by Dementieva in the first set (four of them in one game).
Only at 6-2, 2-0 did Dementieva finally show signs of life. She broke serve then.
But serving to stay in the match at 4-5, Dementieva started off the game with double-fault No. 9. At love-30, she served up double-fault No. 10 – matching the number of foot faults she was called for during the match.
She saved one match point, then a second with a good first serve, but couldn't save the third.
Serena let out a massive screech of relief after it was done, as if she had been saving that one up the whole time.
The win gave sister Venus at least a shot at being alive in the event.
But Venus would have to beat Svetlana Kuznetsova, and more would have to happen after that. …

BMSO helps shoebox appeal
Broadstone Mill Shopping Outlet has recently started supplying unwanted shoe boxes to Norbury Parish Church Hazel Grove, for their shoe box appeal.
The church has run the shoe box appeal for many years and sends the boxes via International Aid Trust, a humanitarian Christian organisation based in Preston. The shoe box team consists of volunteers, some parishioners, who decorate the boxes with bright and Christmas paper, then fill them with useful items and fun gifts; hand knitted hats, gloves, hand puppets, toiletries, school supplies. The team, co-ordinated by church members, works throughout the year to supply items to fill up to 250 boxes, which are sent to children in eastern Europe, Africa and Asia.
They are very grateful to BMSO for providing suitably sized shoe boxes for their appeal.

This weekend, I picked up a bottle of tequila with the idea for this cocktail in mind. It is not low in calories by any means and should be considered a Paleo friendly treat, drank in moderation. (Sorry, I don't practice what I preach!)
Watermelon Margarita
makes 1 pitcher
6 cups watermelon chunks
4 large limes, juiced
1 tbsp agave
1/2 bottle of 100% agave tequila
Place half of the watermelon chunks in blender and blend. Pour the juice in a pitcher. Do the same with the remaining watermelon and pour in the same pitcher. Add lime juice, tequila, and agave to the pitcher. Stir, pour, and let the fun begin!
I made 2 pitchers, which was too much since my sister was on call, my mom and bestie are light weights, and I didn't want to be a lush alone. The second pitcher was barely touched, so I poured it in a plastic container and froze it. I can't wait for the weekend so I can take that slushy goodness out of the freezer and slurp it up!
I might start a regular little cocktail installment on the blog, including drinks with only the freshest ingredients. What do you think? Would you be interested in ideas for refreshing, healthier drinks?

Okay, so I like composing music and all, but I'm usually at a total loss of creativity and I really have no idea what to make.
That's where you come [email protected]
I'm offering to make songs TOTALLY FOR FREE, on request. That means, you tell me you want a song made, tell me what style you want it in (meaning, you direct me to an artist, or you give me some other information you'd like in the song, like a drum loop or melody) and I make it.
The reason I'm doing this is because I feel I work very well through imitation – actual ingenuity is really, really hard to grasp for me, I know. But through imitation, or maybe even through request of friends, it might be easier to make.
So… anyone want a song?
