my problem with getting facebook chat to login was my username and password always came up as being wrong, after i setup my username. the solution to this was to logout and log back in.

http://developers.facebook.com/docs/chat this is some info on facebook chat.

the next problem i had was although facebook chat logged in, it always would disconnect adding all the fb friends to my contacts

from the information on the page linked to above, i think this problem is caused by me being behind a router. therefore this problem can be solved by either forwarding port 5222(or enabling upnp, i imagine), which at the moment, is too much hassle for me.

this leaves me wondering, why does the app use port 5222? and in the advance settings, why bother with including a stun server when the chat doesnt even work behind a router.
