I was going back but apparently you shut down the server. I did some test but I'm not sure if this will work, because I needed another person for test, but still try. If you knew their are other tools like magma cream, blazing rod and blazing powder. With magma cream you can restrict, in theory, all players except yourself, but if you want others to access it you need to do som file changes. So to set multiple ops go to your $YOUR SERVER FOLDER$/mstore.Then go to another file called massivecore_mconf and open file. Then in permissionDeniedFormats "some.derp.permission.node.1": "derp". Change derp to a person you want to op. Hope this helps.
