There is a mapchooser pluging either in ur plugins directory or under in the pluging/disabled. If it is in the disabled dir, move it up into ur plugins folder. On the firts run (console: sm plugins load mapchooser, or simply change a map) it will make a mapchooser config (mapchooser.cfg) file under cfg/sourcemod (it think, but im not sure). Its easy to configure it!
