I think that the /res message command should have some more options. We already have %player, %owner, %colorplayer. I think we should have more than just three variables. I don't know about you, but I would like to greet players with a message such as: "/res message enter &aWelcome %colorplayer&a, to %colorowner's &aResidence."
Did you notice the color part? I just think it would be better for people to see what rank the owner is.
