I don't want this populating contacts - as well as not being always on - so I entered the settings on Pidgin... no idea if it works as I don't seem to get a buddy list. Anyone had any luck?

I've enabled it, and it keeps giving it as <user-name>@chat.facebook.com/

the slash keeps appearing. I've switched off SSL in advanced settings, it was set up as a XMPP account.

settings used are in this thread:

I can copy them over if necessary.

Edit: I re-entered my password properly. Must have entered it wrong. Thanks everyone!
