The Mod adds a functional auction house and shop to the minecraft world.
it is designed to stimulate player driven economy with the custom items from its companion mod Chris' RPG items which drive prices. The Mod itself is dependent on the other so they must be run together.
Part of the shop is listing the rpg items for sale to drive monetary purchases.
Another aspect of this mod are server controlls. It creates many different commands and a whole reporting banning and moderation set of rules to control the player base, including a auto obfuscation, muting and bann mechanic in place for fowl language.
