Hey man, see if TAW is suitable for you. We got players on our unit from NA, EU, and Australia. There's a thread below this one about The Art of Warfare...or you could check taw.net to see if the looks fit you.
GI unit right now is small, but growing. We're actually looking for some admins for it, so maybe you might get a bigger role than just a normal member. TAW is one of the world's largest active gaming clan with nearly 2400 members (in a dozen+ games) across more than a dozen nations across the globe...so we are established and not any fresh community.
