Frank Kern is most known for his "Mass Control" (and lately updated as "Mass Control 2.0") course. You can see review of it in his own words on his site here: http://www.masscontrolsite.com/supersecret.php, at least while it's still there. Once he puts it down, I'll appreciate a comment to this page saying that I should update it. He also seems to do active consulting, at least for his friends, and helped many Internet Gurus to launch their campaigns, for example, Andy Jenkin's StomperNet or John Reese's Opportunity.
His "Mass Control" course is essentially about how to sell more and at a higher price by building relationships with prospects in a Web 2.0 style: friendly, building trust, making a lot of loyal followers. It starts with a small philosophical introduction and "Four Day Cash Machine" and then followed by the actual 30-days home study course. According to Frank, his Mass Control system consists of four parts: interest and desire, trust, proof, and samples. If you want to know more, well, you may have to wait until he'll decide to offer his system again (when I am writing it, it's still available, but I am not sure if it will be the case when I'll publish it, the claims are that his stuff is normally sold in minutes).
I am publishing Frank in the Hall of Fame section for now, but considering what he did, he probably deserves to be on Olympus along with Jay Abraham, Dan Kennedy and Rich Schefren. Please, vote for him if you think so too and once I get enough votes, I'll move this article there.
thanks
