When I tried to login - I couldn't...in fact it seemed to kill all my network connections until I closed the game application.  This was after it gave me a "failed login your password is wrong" screen.  The only way I found that I could fix it and login was by logging in to Impulse first (actually via Forum login here.)  Once I was logged in it let me connect...This seems weird - maybe it was just a weird coincidental timing issue and the login server was down and happened to come back up.

Also - when trying to join someone's game that was passworded - didn't know it was passworded and tried to join - didn't enter a password and even clicked "Cancel" - it stuck me at "Attempting to Join."  I had to CTRL+ALT+DEL to get out.  There should at the least be a thing that shows if a password is on a game at the lobby screen - and obviously there should be a more graceful cancel.
