Manhattan Direct used to run (may still run) very expensive seminars on how to make lots of money over the internet. Very slick marketing, but the content of the seminars ? well, not too hot !!! :( However, you too can make a million if you get 100 people to fork out £2500 for a 2 day event.

It's a good idea to search extensively on the net on the topics / key words (most of the stuff seemed to originate via Bill Myers and other gurus in the states).
