Yeah, the b2 window looks funny. I appreciate the Post thing got bigger, but the b2 window looks funny as ever. I'll upload a picture later.

By the way, the login form does not have the username and password fields in line with their descriptions.

But on the whole, I'm pretty satisfied with the UI, except with the Teams thing. Well well well. We could break it down into two things:

1. a pop-up window
   
2. integrated into the b3 interface
   

While pop-ups aren't good news for Mac users (it auto-sets the windows resolution for IE, damn), I would feel that integration would still be the second best thing, if it was given as an option. Maybe it could be turned off by b3 after there is too many users.
