I'm in a pretty popular clan called Unreal Zark Alliance (uZa). As you can guess by the name, it originally began as an Unreal clan. We eventually moved over to Call of Duty and we now run some of the most popular servers for CoD TDM, CoD:UO TDM and now 2 servers running CoD2 TDM. All of these servers are always full with 32 players each!
Myself and a few others are trying to get some popular Q4 servers running now as quite a few of us love our Quake series games. We've started out with just an FFA server but we're having a hard time keeping people on it continuosly for some reason. If a couple of us from the clan get on it, then people start to pile on but for whatever reason we can't seem to keep it occupied.

We may try TDM next to see how that goes.
I really appreciate all the input guys!
