Bukkit

What is the enhancement in mind? How should it look and feel?

Please provide any additional information below.

I would first of like to say that this plugin is amazing and I really appreciate the effort you guys are putting into it. I was wondering if there is a ranking system with permissions in it. Where you have to have a certain amount of points to unlock a certain class. I great example would be the zombie horde server. I'm not sure if their is already a feature like but if it is could you tell me where I would go about doing it.
