SFI is an outstanding program where they have more possibilities than just on TripleClicks.
Here they can make their own team,do the Pay Per Action program,earn on their second home CSAs they dont have that possibilities just on TripleClicks.
There they only can play games,buy what they need,bid on auctions,but they can never earn that much as long as they do both programs SFI and TripleClicks combined.
