First off: 1. I need a plugin that can separate different money in different worlds (Example: If I had $100 in world 'world', I could change the config money amount in world 'world_nether' to $200, therefore even if I had $200 in world 'world', I would have a different amount in world 'world_nether' kind of like multiverse inventories). 2. I need a plugin that can disable plugins in certain worlds.
Not sure you really can, but you can remove accsess to commands via permissions in that world and most decent plugins that effect the world in some way have a multi world option, so you can "disable" it in that world.
No you want to edit the permissions file through text and add it to the groups you don't want to use factions
I know factions has permissions, but apparently players don't need them, they just use the commands. Is there a config thing called permissions_enabled = true or something?
