I came up with a method of displaying a link to Touchstone on access denied pages in Drupal 5.x. This would probably work for Drupal 6.x as well. Here is how I set it up:

1.) Create a new page node. Title it "Access Denied" and use this content:

<?php
global $user;
if ($user->uid) { // this user is already logged in print "Access Denied: You do not have access to this page."; } else { print "Access Denied: You do not have access to this page."; $dest = 'https://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
