Pastabilties is quite similar to your FC. A good chunk of us (me, GM, and some of our raiders) are IRL friends that used to raid together in WoW. We currently have about 14 (Don't quote me on this) members in our FC, about 10 active. With guild alliances coming out in 2.1, I'd love to discuss this idea with you more. Add me, Chopper Man, and we'll talk more later
