Hi I hope someone can help me out here, im looking for something to do with factions/permissionsex or something else that will only allow certain people to join/create factions ie if you have a 2 sided server one side was people who live in trees the other people who live in caves (just an example) what would i have to do to make it so if someone had the pex rank "tree" and they make a faction, anyone from tree rank can join how ever people from cave cant? Thanks hope someone can help
