Permission Nodes
Permission nodes depend on what groups you have set in your configuration files for rank changes. If you have admin = Admin set in your commands.txt configuration file then the command /admin will be used to change (promote/demote) a users group to Admin and the permission for this command would be mcftpromotions.admin.
Promote/Demote to Group
mcftpromotions.<command>
