I can get a 4v4, tops 6v6 team for COD4.
Also signing with MLG, might not be such a great idea, we all have seen what MLG did to GB; also SONY seems to be working with MLG now and GB, KZ2 has held tourneys there.
So although MLG would bring much attention and sponsors and such, it will just turn the site into another GB, with people just flocking here for the prizes/money, rather than the fun and competition.
Another thing, if divine knights clan field several 4v4 teams on a tourney, why not make the tournament like horsemen, that way anyone can make a team, clan mates or just forum friends.
