2 - This is not just for beginners on the internet. There are a large amount of marketers that joined to learn more and love it. So the coaxing part you mentioned.... not really there. You can stay a free member but you just don't get the info that premium members get. You seemed to be outraged about that. Well how about you give your services away to anyone that does not want to pay and then charge the ones that think it's worth it. How soon before you are called out and you have no business at all. So that complaint is just non-sense.
