Well while i was searching on Google i found perms for 10 different plugins but not for Iridium. Even the owner of the server couldn't access deleting the /is. At the end he somehow did it, but still in a long term way we as a brand new opened premium server would love to know more.
If there is anything addable. I dont want to post a link of the other plugin for which i found /admin perms to accessing commands like that, so if there is any more info on this.. we would be thankful.
