Although I have mentioned this resource in the main page I have not actually written much about it.
The Network Marketing Magazine run by George Madiou is on a roll in 2008 with a number of special deals in its membership drive. The site has recently completed its Resources section and it has tons of valuable tutorials and guides for the newbie and veteran alike.
The monthly publication is also not short of contributors and often on a specific topic like Training or Prospecting. As a member you can download their archives right back to when it started some years back.
If you are looking at new sources of information on network marketing, you might want to become a member and take a look. A free trial membership will give you a taste of what it has to offer.
