I know I've suggested something similar to this before but it's a little different now and maybe it could reach out to all players of Tremulous.
You should have, 1 tournament (a week, maybe every 2 weeks) for beginner's to learn how to play properly and get better so they can then go on to joining clans, and bigger tournaments
Another one with the same or similar amount of time between like above (tournament every 1 or 2 weeks) for the more "advanced"/better plays of Tremulous who want to just have fun with other people who aren't in clans or one that isn't based on clans kicking the crap out of each other for fun or rivalry. Like, somewhere just the good people can go to get away from the clan shit that they're in everyday.
