BoB, DT, and S8N have all made a number of decent maps. S8N has also contributed a number of other graphics (textures, models, etc.) Bain has done an amazing amount of work for the community -- mostly on the coding and organizing side of things. I'm always surprised with how much crap he puts up with. I know he's shelled out a ton of money to keep servers up and running, too. If everybody else in the community could contribute 1/10th of what he does, we'd have an amazing thing going here. I don't know too much about Blitz. He tends to be pretty reserved. I haven't really seen him say much. He and digi are certainly skilled from a raw playing perspective, though. I'm not too up on the rest of the er33t roster, either, so sorry if I left anybody out.
Not to get off-topic -- and perhaps another thread should be started for this -- but what is the BF matching system like? It would be nice to get a little more organization in the clan scene.
