Hi, as far as I know, here in SFI has some "power tools", say, "PSAs To Go", "S-Builder Co-op",etc, which are designed to help each affiliate to build his/her team quick and fast. You can buy them.
Besides, you can use traditional way of promoting your SFI links at socila media or pay-to-click or pay-to-sign-up, etc, to get your affiliates.
Or you could inform SFI and TC to your friends or family members as well.
Hope this helps.
