First: Define beta..so that I can't just slap a b on the end of a dev textured map, and call it a beta. Second: Have a way for community members to rate those betas (I think you have an alphabet system in the DL section, but I haven't really checked). Third: Take the top 10(15?) betas and contact the authors. See if they can make an appearance for a minimum of 30 minutes one night during the week (M-F) at 7:00 p.m. server time. If so, include their map. If not, don't. Fourth: Put those maps in the mapcycle and remove RTV. Fifth: Encourage people to show up at 7:00 server time. If you have high quality customs in a rotation, and people playing at the same time every day...I think you can build a playerbase. At any rate, if you can get 8-10 people to show up at 7:00 p.m. server time (playtime for most people and in the same time zone should be decent ping)..you can draw people to the server.
