hi need a plugin , 1. so that playersdo not break the buildings of the Op´s and the other is for so that each player has his house and no one steals or breaks. thanks.
Did you even look...? WorldGuard protects buildings. And another I forget the name protects blocks placed by people.
Or you can use Residence plugin. It's also zone-protecting plugin. I have only good experience with it. Could help you, if you'll have any problem with it
