we have a call mod button, you just might not realize it. you take a screen shot, save it to your computer, and send it with the contact form. the mods i know check their email regularly when they're on their computer, and there wouldn't really be a faster way to get ahold of them, so they should get those emails and often respond to them quickly.
if you were referring to the button "summoning" mods if they're in any other room/game... i'd say that's probably more hassle to program than it's worth. it'd be easier for you to scan a few rooms to look for a mod (or better yet, know a place where a mod often sits when you're online).
and the most efficient answer... mute button. doesn't prevent others from being bugged, but it does mean you don't have to listen anymore.
