one suggestion i've had is to create a day for each server a week. like monday: gun-game, tuesday: min-game, wednesday: unlimited, etc. obviously, you don't need to play only there those days, but it could be something that admin or ppl who like all the different variations of cs:s to help try and boost not just one server, but all of them. could possibly get a lot of new ppl interested in not just a server, but the community. or it could backfire and get no new ppl.
