given how communication in graal is currently structured with PMs and Masses, I think it'd be a good idea to allow the creation of "channels" within the player list that would allow players to communicate with people with similar interests easily rather than have to mass message everyone and possibly send players something they don't want to see
I imagine this will be possible with V6 anyway by modifying the playerlist by script, but I think a built in functionality would be better and possibly allow for cross-server channels
