This is a mod with which you can connect to an online ragfair server, sell items to others and buy items from others. This mod is cross-version, in other words, players of version 2.0.0 can buy and sell things from and to players of version 1.5.1. And selling mod items is also supported.
Note: currently it's not allowed to upload the 2.0 version of this mod which is compatible with 2.0.0 RC1. Anyone who wanna give it a try may pm me and I'll send him one when I saw the message.
