This is extremely tricky question,but requires a logical answer.
First, You must look at your experience at SFI..Are you happy & enjoying your participation at SFI?
Have You been able to generate a decent & regular income from this venture...if your answer is YES! Just tell the 'whole world' including your family members to benefit from SFI...
But, if your experience is decimal...what are you going to say..I wonder?
