StackEdit is a very nice Markdown web app editor that works off-line. I can publish as HTML, but adding a WordPress plugin to work with Markdown is an option. 


Start a new post while offline
As it works offline, you can create any number of documents and update/upload when online
Lets me edit posts I created already with the program
You'll copy the post content in a new SE document and publish it against the same post ID
Spell check
IMHO, that's browser territory
Uploads new posts when I reconnect
After reconnecting, just hit the publish button and it goes live
Has the same features as the online editor (i.e. toolbars, WYSIWYG and code editor)
Just basic features for the editor
Free (as in beer)
Yes.
Works on either Windows or Mac OSX
Yes.
Edit posts currently on the website (with an offline copy)
See Upload when reconnected

Offline WordPress post editor/creator
I logged into the Ubuntu 12.04 LTS and instead of installing it... I pressed the Log Out button, thinking of installing it some other time.

But then a screen appeared asking for Username and Password.

I typed in my name as the User name and a password of my choice..I was halfway through typing my password..just then I remembered that I had to Login as 'root' so I hurriedly pressed the Back button... but instead the user name and half password I typed.. got submitted.

Now it is asking for User name and Password and when I type the ones which I had initially typed..its showing Login Error :(

But the problem doesn't end here... m unable to shut down my laptop.. its been more than 12 hours and m stuck at this login screen... plzzz help me out!
