alilsassy: The chat room already does tell who is "present". It looks like it lists people who are either on the "static" page, or have the actual chat box enabled. It looks like it is split up in to 2 parts. From what I have seen, when someone has actively typed something in the chat box, their name goes to the top section of the list. After a certain period of time, it drops back down to the bottom part of the list.
