Orbconomy
Orbconomy is a simple (SuperPerms) economy plugin for minecraft 1.8 and beyond.
It allows you to use your experience points as currency in supported plugins (support will be added to register soon) giving a way for players to earn currency with no additional plugins - as well as giving them a real drive to earn those experience points!
There are only two permission nodes
oc.user oc.admin
These commands affect the commands that you have access to - using the /exp help command in-game should tell you more.
