Hmm, I think the discussion is pretty civil and the points adressed quite valid.
People should be held responsible to their POVs, as in; if someone on a quake3 forums comes up and says ‘hey guys, i want to make a red-team-only CTF clan’ they would not find nearly as much civil responses as provided here.
To me it seems as the OP is just misinformed about what handling clans, or at least doing that in a team-oriented, assymetric gameplay like this, is.
The game is not gonna get released in half a year or so, hosting a clan now seems… premature, particularly with restrictions like that.

its allways a good start to have a “professional looking” website, goodluck!
