So basically here's what I need help with. I want to have multiple worlds, but I need it so that depending on what world your in, for you to have different permissions. it seems like this is possible since in Group Manager, the files are located in worlds(which world)/world(the world for permissions)/groups.yml. can anyone tell me how to do this?
yeah, the system is set up so that it's fairly easy to edit the permissions for multiple worlds. Duplicate the entire permissions folder of your first world (../plugins/GroupManager/worlds/<WorldName>), then rename the second one to whatever your second world's name is. Then open the new folder and edit the permissions to your likings, and then /manload in game.
