Guest have a option to move to another server anytime, or signing on there formally.
After while, 2 weeks or so?, server can push out guests to another server which has guest hosting capablity.
Good point is, getting rid of stress of server selection, and new comer got experience to move server in starting term. And many server can join on accepting new comer inviting. Some people may keep guest mode, it’s funny I think.
