I actually signed up for this a while back. I subscribed to the e-mail thread, and all I ever got was spam saying to 'Buy Now! 50% off! Buy Now! Techniques for _____ (etc...)" I think that there may have been some notes struck here, but it is definitely for a monetary pursuit and not for a genuine spreading of lucid knowledge. I personally would discourage listening to these, but if you really feel like these could work, why not? Everyone is different. They may work, they may not. Definitely a cash cow, this one though.
