The facebook connect portion doesn't work. I tried to log in via it and it gave me a variety of errors, including that it couldn't find an email address for me, that there was a client/server error, and that it couldn't reach facebook. Refreshing fixed everything except the email address error (which happened on the same page where you put in a nickname and it checks to see if the nickname is available) - should be able to fix that by adding a similar email field.
