Did anyone try the Elaton program from livestutterfree.com. It costs $6000 and its students claim to be stutter free Here is the link http://www.livestutterfree.com/. $6000 seems incredibly steep for pretty much a three day skype session. I was wondering if anybody had any experience with this or not. Is it reliable or is it a scam?
