CHATBOX NOW HAS AN "AWAY" BUTTON
I added a button to the chatbox (on the far right, looks like a door) that allows you to set your status as "away". Click the button again and you'll be back.
The purpose is to let people know when you are logged into the chatbox but not at the computer.
This isn't bullet-proof, but it seems to work. Let me know if you encounter problems with it.
