      <h3>Quick Questions</h3>
      <h4>I don\'t want people to see the edit link/be able to edit my site!</h4>
      <p>Those edit links only appear to you when you log in to the site as the admin.
      The public will NEVER see them and even other users with accounts won\'t see
      them unless you give them the rights to be able to edit something.  To get rid of
      the links when you visit the site you must Sign Out of the admin account.  You
      can do this from the administration pages in the upper right-hand corner.</p>
