There is one website that hosts training calls specific for the MLM industry, called MLM Teleclass. These are complimentary hour-long conference calls that are generic to the industry and covers many aspects of building your business. The teleclass leaders are heavy hitters within the MLM industry as well as self-help leaders. Go check it out and see what they have to offer. They have a fairly large list of teleclasses for all.
On the same topic, another site that hosts training calls specific for self-help is Training University. Similar in style to what I mentioned above, Training U also hosts complimentary hour-long conference calls to the public.
If you're outside the US and want to save on these calls, I highly recommend that you use Skype to call in to join the teleconferences. Skype is presently the cheapest utility on the planet to make calls to landlines and mobile lines. You just need to purchase credits with Skype using Paypal and you're on.
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.
