The most important thing, in my opinion, is to remember that affiliates joined SFI to build a business and make a profit.
There are number of products on TrippleClick store that can help in a big way to build a business of a new affiliate.
For example: S-Builder Co-op, Wave3, TCredits and many more. As your affiliates will learn about these products they will use them and promote them in a very efficient way.
