Hello,
I think that both of you can help in SFI, perhaps some auctions grads can make you earn more if you do a good advertising and other people sign up to Tripleclicks to participate in these auctions, but also Eager Zebra is a good reason to earn, because you can parteciapare with few TCredit to all games and win daily or monthly hundred TCredit short, both are part of Tripleclicks, all two give you the opportunity to earn.
