There is a known issue with Firefox 2 and the Chatroom:
Symptom: If you log in to the chatroom having previously logged out then you may not be able to see anyone else in there despite the fact they can see you.
Cure: This can be cured by clearing your private data using the keys [Ctrl]+[Shift]+[Del] pressed together and then clearing your cache. Optionally on the menu bar: Tools>Clear Private Data
More details - if anyone is interested!
