I just learned about chess.com greeters. It is only for online turn-based games, and I was wondering if there could be live chess greeters. I have yet to do the greeting thing, so I don't know much about it. Just wonderin'.
This idea definitely has potential, since chess.com is not solely a CC site anymore. You could try turning this into a site suggestion on the appropriate forum.
Oh sorry, I should've provided the link in my first post. Anyway, I think you should try Site Feedback & Suggestions (click).
