title: Adding New Admins to Active Admin
body: <p>I am using devise for my users. I recently installed the rails <a href="http://activeadmin.info/">Active Admin gem</a>, everything is working beautifully. </p>
  
  <p>However I can't figure out how to add a new admin users. I can see that active admin created an <code>admin_user</code> table in the db with a user admin@example.com, which I use to log in to the interface.</p>
  
  <p>I tried adding <code>admin_user</code> as a resource so that I can just click the Add Admin User button within the active admin interface to add a new user, however that does not seem to work.</p>
