It's a good idea to be honest. But I think there's a flaw to it. You can't really stop griefers from invading homes. But it really is a good idea. I have had no luck in finding working mods for members to protect their homes, chests.
There was a working one, but it allowed everyone to be an admin and there was
an admin command that can allow the wiping of chests. I am still exploring into it, believe me. I just have not figured out how I can make members access member commands, rather than admin commands.
