Try joining NZP (Nazi Zombie Pros) or TZBC (ThatZomBClan) They both have existing members. Less work for you. Instant access to good players. And it will make the existing zombie clans stronger. Stronger clans means more possibility to play games at a time that works for you. To apply to NZP fill out the Application in the "New Members" forum here:
Or TZBC Hit up "ThatZomBPlayer" On ps3 to request a tryout.
Or keep doing what your doing and best of luck with recruitment. If you get more than 4 clan members hit up NZP for a grief tournament request. We love new competition. It's hard to come by these days.
