I personally dont use this plugin, I just ban greifers. But I wanted to let you know that it works and it works well! I saw some people commenting and saying it was useless, and I don't like when a good plugin gets a bad review over an opinion. So I wanted you to know that it works!
@LDX: change gamemode force the player to reconnect. This can be done on the fly !
@Anonymous: stop that bad comments, this plugin is very usefull and simple... not too many commands and useless stuffs !
@linuxboytoo: if you want help to implement specific world buildmode, im here !
