I was a member of Stiforp for just over two years. I paid a monthly premium and even paid to upgrade to 3 Star ranking. I won't disclose the cost involved over the period of time, but non of the promises were forth coming. First promise, you never have to sponsor anyone to earn some form of re-numeration, Secondly, with the number of people joining in the thousands you will get spill-over into your team. "You never have to sponsor anyone to earn a commission".
The websites, autoresponders and landing pages are good to look at and try to promote, but no have ever worked for me in the two years as a member. No commissions and entitlements. In fact my last visit to my home page I found I has lost the 3 Star ranking which I paid for some twelve months earlier, and with no notification of any changes.
Questionable activities to say the least.

I've also been in a number of MLM and affiliate programs as well, but SFI is the only one that doesn't ask for credit card details to join. It also has all the FREE stuff at your disposal to build an online business in the form of information, upline support and training, all for FREE.
Sure, you will need to put funds into moving forward, but that's your choice. No one is telling you that 'you have too do this' or 'do that'.
I am a team leader and email my team every week congratulating them on their progress and dedication. I always tell them it is their choice on how fast they progress and what the benefits are. So far this is the only program that I have actually received payment for my efforts. SFI is a genuine marketing program.
