Grand Exchange adds a command-based marketplace to Forge servers. It is a server-side only mod, so players do not have to install the mod to join your server and use it.
Almost anything can be traded on the marketplace. The only things that can't are Enchanted items and other NBT tagged items, such as Written Books.
This mod requires Grand Economy to work.
