Wildcard link for user menu
You cannot use menu wildcards like that. You need to use the following code.

  &lt;ul id="userNavigation"&gt;
    &lt;li&gt;&lt;?php echo l(t("Profile edit"), 'user/' . $GLOBALS['user']-&gt;uid . '/edit'); ?&gt;&lt;/li&gt;
    &lt;li&gt;&lt;?php echo l(t("My posts"), 'user/' . $GLOBALS['user']-&gt;uid . '/track'); ?&gt;&lt;/li&gt;
    &lt;li class="exit"&gt;&lt;?php echo l(t("Exit"), "user/logout"); ?&gt;&lt;/li&gt;
  &lt;/ul&gt;


The global $user is the user object for the currently logged-in user. Be careful: It is not a fully-loaded user object. If you need that, you should use the value returned from user_uid_optional_load().
