Okay, so when I place a block, people are complaining turn it off. They say it says This is mariotime33's block, or whatever, how do I stop it? I know it is something like /bp, but it didn't work. Help! Nevermind, it says "This block is owned by Mariotime33." Not the other thing. Help still!
assuming this is in easy, /wallow username allows you to enable another player to edit blocks/decoration items you have placed. for example, if you used /wallow hamsrus1, and I was trusted in your claimed area, I would be able to break things you have placed. if you use that same command and I'm not trusted to your claim, I would only be able to edit your blocks that are not claimed. (you should claim everything you build)
I also added the command /friend <player> that does the same thing, which is easier to remember than /wallow <player>, in my opinion.
