 *       If these are really configuration settings then we can add those to the dokeos config settings.
 * @todo move display_courses and some other functions to a more appripriate place course.lib.php or user.lib.php
 * @todo use api_get_path instead of $rootAdminWeb
 * @todo check for duplication of functions with index.php (user_portal.php is orginally a copy of index.php)
 * @todo display_digest, shouldn't this be removed and be made into an extension?
