Well, you could make a movie where, you show every class of the game, and a short briefing under each clip with this class and its specialities. And show ppl that it's a game with alot more to it than just killing each other, by showing the the different game types, and then maybe when you get to the part where you show them Deathmatch "And ofcourse if you just like to kill ppl, theres always Deathmatch :P" By showing them this, we would maybe get alot of ppl's attention, and ofcourse if we make this movie ourselves, it would also be free PR for the clan :P
But that's just what im thinking of...
(By the way, i have no idea how to record the game in the best way :P since if you use a videocamera it will often interfer with the screen...)
