For many years my server was open only to my friends and family. Recently I have opened it for anyone who will sign up on forum and write a post. I wanted to protect my old buildings from random griefers, so I have created a region containing all of my old buildings and added my friends and family to the owners group that can edit that region. Now is my question: Is it possible to automatically add new players to the owners of the region after they spend certain amount of time in game and/or place certain amount of blocks? Maybe there is alternative way to deal with new players and keep my old building protected? Any help/suggestions appreciated .
