I am the server Administrator and I am trying to test out something with Client Permissions. I have had an issue with other Admins messing with revoking ranks of other admins. I have had this done in the past but I since forgot how to do it. I have it so said person cannot kick/ban or move me. But I can't figure out how to disallow them from revoking my rank.

Under Client Permissions which do I modify to fix this issue?
