Hello, I'm sure there is a plugin out there already for this but I have looked all over and can not find one. I need a plugin that you can type /rankup and they can get promoted to the next group for a certain amount of money. I have made all the groups in PEX but I need a plugin that lets me use those groups and make it so they can /rankup to get too the next. I'm creating a prison server so this is very essential. Thank you for reading this.
