Hi there ! I am trying to get up my server, and I want it to be economy based. I am wondering how do I allow people to use a command such as /rankup to become a higher rank, and also making it automatically taking money away from them. I have groupmanager and Chestshop... Please suggest what I can do and if you suggest replacing the plugins I saw that most things require "Vault" but I have no idea what it is, as there are no videos on it and very minimal information. Thanks !
