#This plugin will work for normal worlds, It is just not
#optimized for that yet. When a player is teleported, all
#of the blocks around them are set to air to prevent them
#from dying. This plugin was made for a flat world so
#use at your own risk. Don't want to take your chances?
#then try it yourself before giving players the ability
#to use this command.
