Hey devs, I was wondering if it would be possible to create a plugin that allows a player to click a sign, and be charged x amount of iConomy currensy to change his/her permissions group (Permissions 3.x)? Basically, I'd like to use this to allow players to buy classes in the Heroes plugin, without me having to be online and edit my permissions .yml everytime someone wants to buy a class on the server. Not entirely sure if it's possible, but if it is, I'd REALLY appreciate it!
