I have had it about 2 weeks. It's a good program. Guarenteed to stop cheating. It only allow certain files in your .pk3 . If the server has mandatory files then you have to download them or some with have optional files. It seems to lag my computer for about 1 minute but then it goes away. People tell me theres runs fine, maybe it's my crappy computer. The servers you choose from all run missionary so it's guarenteed cheat free. Also if someone runs an aimbot in the backround, missionary catches that and kicks you. In order to setup a server you have to tell ^IW^ and they will set it up.
It also checks the size of .pak files so you cannot alter anything without it knowing.
