Please review my new social learning site
apsurd: To me, the signup/login forms are not clear. You use "login" on the signup form. I instinctively associated that word with logging in, so i kept looking for where to "sign up". A better word would be username.When signing up using the big orange sticker icon on the right, you get no status message as to what happend after submitting the form. It was only after trying to sign up using the top left link that it told me "username exists" which meant the sticker signup apparently worked.Not requiring a password on initial signup tells me you want ease signing up as much as possible; why are you requiring email validation then? Seems counter-productive. 
Let users gain instance access, and then delete accounts that haven't validated after a set timeframe, (with reminders).Minor pet peeve. The facebox boxes have too little padding on the left/right margins. It does not look nice.I tried to sign up for a course by clicking on the plus sign, but after I do that I am lost as to actually how to "take" the course. Maybe this is a lack of content issue, but I'm still puzzled as to whether these courses have video, audio, read like a textbook, or??That is all for now.
