If you don’t know what MLM stands for, you must have been living in a cave for the last several years.
Multi level marketing often has a negative connotation and people run the other way when they hear about another product offered by a company who wants you to join up.

Online MLM is often called network marketing now days. This new term seems to have a friendlier feel and the idea is that you are sharing your experience and the benefits of your business rather than the hard sell of trying to get people to sign up under you so you can make residuals off their sales.
