jrock in response to this statement... "sign up for IFSL's program also...it's not mandatory correct?"
I don't know for sure if it is mandatory, however if you don't sign up for IFSL's program, IFSL will not add any people from there marketing effort to your network... Put another way you have just joined Xango as a distributor and nothing else.
However, if you join IFSL program, you don't have to do anything, they market the program and add people to your network for you.
I have done nothing and I have seen my network grow.
This is where the combination of IFSL and Xango is unique in my opinion, normally when you join a network marketing group you have to do the marketing and sign other people up, but with IFSL you basically get to pay them to do the marketing for you.
