NPC Request Thread. (Admins and Managers Only)

[Pkengine]

I don't know if this is possible but is there anyway to make a pkzone into a nonpkzone on command by maybe a chat message or a certain account entering the level? Is there a command I dunno about? o_O!

EDIT: err... I mean making a switching pkzones on and off on command by chat and certain accounts entering maybe thats easier to understand -_-
