            </form>';

            echo $stroutput;   
            }
        else
            {
            $stroutput= ''.pun_htmlspecialchars($pun_user['username']).' ('.$pun_user['g_user_title'].') [<a href="'.PUN_ROOT.'login.php?action=out&amp;id='.$pun_user['id'].'&amp;csrf_token='.sha1($pun_user['id'].sha1(get_remote_address())).'">'.$lang_common['Logout'].'Logout</a>]</p>';
            echo $stroutput;   
            }
        }
?>
