I created a sort of "recruiter" group for certain people who are allowed to add or approve new members to the site, but I see that they are capable of adding themselves to the admin group and thus giving themselves total access to editing, How do I make it to where these people can't do that? Because really there's no reason to even have groups with different permissions if they can just give themselves full access. Also if it's a code or something please tell me how to add it. I have almost no experience in web building.
