Those are two different questionnaires, although they look quite similar.
If you compare the markup you'll see that they're quite different; In fact, even just watching the Network tab of Chrome's Developer tools will show you that the Chakra Healing site doesn't use XHR/Ajax after each question, where The Gabriel Method does; it posts to form1.php, form2.php etc.
Thanks a lot for the reply. I made some assumptions based upon the "look" of the quizzes. I think it was also having to do with some wishful thinking that it would just be a wordpress plugin or something simple.
