multiple chat rooms

[concertm]

I couldn't find this by searching so...
How about there be more than one multiplayer chat room for specific players? Maybe 1 general room for any player and another room for say anyone above MP lvl 15 or so.
I'm getting tired of reading immature conversations and various flaming going on usually by lower lvl players (yes, there are exceptions to this).
Having separate rooms like this would place slightly closer players in one place: a lvl 20 would probably not care/pay attention when a lvl 5 says "anyone wanna play?"
I come to MP to play someone close to my abilities, and I think all of this immaturity going on not related to the game is unnecessary in an MP room, especially when there are the video chat and profile chat rooms where small talk (more like small wars) could take place.

How hard would it be to implement this? The separations don't even need to be by MP lvl, maybe games played or grand score, showing a veteran-like maturity.
