As we know briefing is a thing that happens frequently on the creative server, I think I've thought of a way to solve it using a promotion system. So by default players will not be able to put down lava on a plot unless there the owner of it, and if you have a trust worthy friend that you want to have perms and be able to place lava use a command such as /p promote name . I think this would solve lots of griefing problems. Thanks, staff please consider.
