auto log off timer for chat room

The chat room really needs an auto-log-off timer. Most sites on the internet have auto log-off timers and the chat room here really needs one. 60 minutes without any activity and the profile should be logged off automatically.
This should be standard for the chat room. This site has sooooooooo many fake profiles this would be nice to add to the chat room. Seeing improvements like this to the site would make it better of course. Adding this very much-needed feature to the chat room might even get more paying members.
