A script that I wrote that works with the new Pest-Control update.

If you don't play RuneScape then a Pest-Control script basically sets a world for a channel. This world people then go to because lots of other people are in this world so they'll kill things more easier. If you don't understand the Pest-Control bit it doesn't really matter.

!Setmpc [WORLD] -- Main pc world
!Set4pc [WORLD] -- 40+ pc world
!Set7pc [WORLD] -- 70+ pc world
!Set1pc [WORLD] -- 100+ pc world
[@.!]Pcw -- Displays all Pcws
