Ok, this one will take some programming. It seems like about 90% of the time there is no real topic in the lounge and it gets boring rather quickly so.....
How about a little "topic suggestion box" at the top or on the side where anyone can type in a suggested topic AND next to the box will be a "Like" and a "Dislike" button and everyone will have 30 seconds to vote on whether they like the suggested topic or not (by pressing the appropriate button).
Then once a topic is chosen, it is displayed at the top of the chat room so everyone who comes in can see what's being talked about.
I think it might be worth a try anyway.
