I was reading the forum here for about a month before making my first order. What really amazed me was how much this group of people seemed to have bonded over a PRODUCT. Being a V4L customer and a part of the forum is almost a "secret handshake" thing to begin with! We get the skinny on all the goodies, so I don't feel like I'm losing out in any way shape or form.
I think everyone would have a list of referrals - this stuff just sort of sells itself, you know? The whole referrals thing would become top-heavy very quickly. If every user brings in, say, three more users, who each in turn bring three more users, who each.... sheesh, the numbers get big pretty darn quick. I think I prefer the fun little surprise contests, the freebies, the sales and coupon codes - I feel like an insider!
