Site is working well for me, only one captcha when I established my account.  Not in love with staying logged in after closing the app, but I'll get used to having to logout.  User interface seems mostly intuitive.  I used Imgur for my avatar picture.  Once I figured out where on Imgur to go to copy the image, it was a piece of cake.  Now all I have to do is remember my previous postscript (or maybe not).
