Really we're just splitting all of our players into different worlds. We have like 10 regularly playing people in the old guest world, maybe 50 regularly playing people in the new guest world, and 30 players that regularly play in the member world. With another world the numbers will get even more divided. Remember this is a server not a place to have everyone in their own world. I don't really think the donating world has any thing positive in the long term other than extra money for the server.
