Essential Pranks Collection

This is my first plugin, it has a growing number of commands for loads of fun.
Features
Currently My plugin allows you to create an afk box from a distance with a single command. Also you can teleport people to the void and use the classic irc slap command. More fun features to come thanks to /r/minecraft!!!
