Well, here's another suggestion.
Live updates! I hate having to keep refreshing my page for a message. I think notifications and messages should update live, and the tab should display the number of alerts like in the chatroom. This would be a lot to some users.
The chatroom should have a mention feature, like @username and @everybody. The chatroom messages are usually quiet and you wouldn't know someone is talking to you while in another window or directly to you in another tab. If your name was mentioned, like @Kevin, it would sound a little ding and that means you've been mentioned, look at chat. @everybody would sound a ding to everyone in the chatroom. You could possibly add a silencer button so you don't get notifications.
I think these two things would be a great addition to the forum. Let me know your opinions in the comments.
