For my server, All I want from EE is the Alchemical Bag. Since the introduction of Iron Chests, I don't want to even have the Alchemical Chest, since It's much more interesting (and harder work) for someone to upgrade chests from wood->copper------->crystal. Awesome mod.
However, I have been looking and I haven't found a good explanation of how to shut down access to the majority of EE features, yet allow access to the bags. For instance, I allow players to buy using the economy feature of Essentials starting equipment from a mart. If I could just shut down crafting permissions for all EE items, that would make my life easier.
