MLM Reviews
I pretty much don't like MLM and don't recommend it. That being said, I know boatloads of people get involved and nothing I can say will convince them otherwise.
If you really do want to do MLM, please read this page on lead generation to see why you ABSOLUTELY MUST build your own website if you're going to be successful in this industry.
The main thing is to make sure you are in control of you business, because most MLMers just "sell stuff" on Facebook and as soon as their friends and family stop buying stuff, their business dies.
