I looked on the forums but could not find what I was looking for. This is probably fairly simple but I am just not aware of how to accomplish it. I am using PermissionsEx with essentials as well as a handful of other plugins. However, I want to be able to only allow certain groups to be able to use certain mods i.e. mystcraft. How do I set this up? What is the permissions for a mod, again I understand how to use PEX but just not sure how to use with mods instead of plugins. thanks, tmo
