Chat Rooms – List of rooms?

I have seen installations of better messages with a chat that had a list of available rooms on the left side just as in the combined view the messages of other users in the mailbox are orientated.
Is there any way to realise a list of available to chat rooms or can I really just enter a short code for each chat room on a separate page?I have seen installations of better messages with a chat that had a list of available rooms on the left side just as in the combined view the messages of other users in the mailbox are orientated.
