This is an important question, and one I would certainly want the answer to before I committed to a program like this.
The other question I find to be equally important and would want answered is "If I find this training is not for me, can I walk out at any time with no negative consequences?" If the answer is yes, then I would say enjoy the training and I hope it helps you. If the answer is no, then that would raise huge red flags with me. For example, in that direction lies scams like Scientology and Heaven's Gate ...
Good questions all - questions like that and critical thinking throughout our lives, like ordering something off the Internet, deciding on a cellphone program, or choosing a dentist for your child, deciding what school your child will attend, voting.
Somewhere on the site is the story of someone in their forum who decided to leave, and they just left. I think there is a prorated refund policy, depending on how much of the seminar you've taken - I don't know.
They're a large business, and the Heaven's Gate realm of things is far away from how they operate. The "janitor sweeping the ballroom floor" scenario is not in their realm - scam artists don't last long in an Internet-enabled world!
Bottom line is, that if someone is considering this, or other, seminar, they should be an informed consumer with our eyes open and our brains functioning. But you already knew that - you're a Freeper! :-)
Best...
