And CB servers are pretty crap. You should give
Netgames or
Barrysworld a try.
NG can be laggy, but you can book servers within seconds. But BW is outbooked too far
The command you will need the most are:
adminlogin <pass> / adminlogout
admin set botpack.ctfgame <?>
Timelimit: timelimit <time in minutes>
Caplimit: goalteamscore <score> (0 = no limit)
Tournamentmode (everyone clicks to start): btournament true
Playerlimit: admin set engine.gameinfo maxplayers <number>
map change: switchlevel <name> (without unr. extension)
