Bukkit

How it works:

You start at 0 reputation, and tier 0. As you interact with players mobs and NPCs in the world your reputation will go up or down.

So you kill mobs, your reputation will increase, you attack NPCs then your reputation goes down.

Tiers:

When your reputation gets to a certain level set in the config you will change teir, messages will be sent inform you of this and also server commands can be run, also set in config, allowing server owners to punish, reward players or change their permissions group.

Tiers also affect your reputation, if you are a good tier you will be punished for attacking another good tier If you are a tier 3 and attack a tier 1 you will be more heavily punished than a tier 1 attacking a tier 1

If you are a good tier then attaching a bad tier player will increase your rep not decrease.

Mobs:

Killing mobs is good :) evil mobs can give you extra points for just hitting it points for killing them these are mostly positive points with the exception of a few mobs

Animals - don't give rep as they are to be farmed Pets - tamed cats and dogs will give you negative rep as they are cute !
