but realize if you block them from team games then they will be more prone to form secret alliances in regular games.
Just some desert for thought....
I like the idea though...
I"m thinking though more of there being an option to limit access to games unless you have a certain rank..... say like.... if I want to set restrictions on what player lvls can enter.... I could play all newbies.... or no nembies.... or only lts and sergents..... or only privates.... or stuff like taht.....
Like have a list in the create a game area where you can click which ranks can join the game.

I think that would do nicely. Doesn't solve the whole problem but would at least help.
