This video tutorial covers how to set up a special high powered "server admin" type of server group but in a way that won't let them do absolutely everything. Because you should control what people can do and only let people do what you want them to do. Nobody should have the same level of power as the absolute owner of the server.

This is important, because people who get the same power as you can do things you have no idea about and can really mess things up for you. Permissions are not easy to do by yourself so after watching this you will have a very good understanding of them and the reasoning behind doing things the right way.
