I have already started on this and have all the commands, with the economy system complete. I am having trouble with a shop due to the complexity. And tylerthecreeper1: To do a lock system you would just create a public static boolean lock = false; And if lock equals true have a listener for logging in and if a player doesn't have a permission, just have it disallow them access. And when you execute the /lock command, just have it set lock = true.
