joomla content plugin
  How do i get this plugin triggered in the joomla core "user manager" when a list of user is displayed? <br>
1. I have already enabled in the plugins table but it is still not working. What I have not done? <br>

    // no direct access
        defined('_JEXEC') or die('Restricted access');
        // register the handler
        $mainframe->registerEvent('onPrepareContent', 'plgContentUserswi');
        /**
         * 
         * 
         * @param object Content item
         * @param JParameter Content parameters
         * @param int Page number
         */
        function plgContentUserswi(&$row, &$params, $page)
        {
          var_dump($row);
        }
