      <p>The page module is used when you want to create content that optionally inserts a link into your navigation system. You can also, however, create pages that don't have this link by skipping the link text field in the page form. At this time, not all themes support the link insertion behavior. Some themes, like xtemplate, provide alternative mechanisms for link creation. Pages are also unique in that they shortcut the typical lifecycle of user generated content (i.e. submit -&gt; moderate -&gt; post -&gt; comment). </p>

      <p><strong>edit own pages:</strong> Allows a role to add/edit pages if they own the page. Use this permission if you want users to be able to edit and maintain their own pages.</p>
