Now, normally I don’t take the time to write out about this kind of thing – except that no other blog post has detailed what your connection credentials are – so I’ll go ahead and write those for you.

Login: USERNAME@chat.facebook.com
Password: Your freakin’ Password

If you do not yet have a username (What the heck is wrong with you?  Why not?!) then you can create one at http://facebook.com/username/. (By the way, that’ll also be an email address soon, just so ya know).
