Chatting
Bascially...it's a catch as catch can. If you are wanting to chat, one of the best things to do is to put yourself in the room. Then just go do something else on the computer but leave that window open with your sound on. As soon as someone enters, you'll hear the sound and then you can go back and chat. This doesn't always work (e.g. I've sometimes sat in chatroom and nobody comes in before I'm ready to leave) but the percentage is high to people coming in to talk.
Note...just being on the site doesn't seem to help much. You actually need to park yourself in chat.
Happy Chatting!
