Well, I think this would make people send PM's to mediators instead of using the request mediator button.

well, then there should be like a off/on button so when the mediator knows he's going afk, he turns 'off' his mediator tag or something like that maybe?

Sure, sounds like a nice idea.

This will have to work: http://forums.d2jsp.org/index.php?act=stash&a=109
