Chat question, and suggestion.

Any way to make the site-wide chat windows start minimized for users, when the first login? On my site, it always opens fully on login.

Also, in testing it seems that a troll could "Chat Request-Bomb" any user by repeatedly requesting to private chat with them, thereby opening LOTS of chat windows on the other user's page. I think this needs a timeout, if the user declines to private chat.
