Way back in 1990, as a stay-at-home-mom raising kids, I studied from home through Buyers Network Unlimited, one of the biggest Multi Level Marketing networks in SA and I obtained a Diploma in MLM.  At the time it seemed like an exellent opportunity for masses of people, from all walks of of life, to earn an extra income parttime or fulltime. The rewards depending on the effort you would be willing and able to put into the project, setting your own goals, etc.
