The January 2009 issue of FeedFront, the official magazine of the Affiliate Summit, is already out, and I am privileged to have my article in it. It may be found on page 24, and in it I discuss the importance of having a call to activation interwoven into the very fabric of your affiliate program. FeedFront is a free subscription magazine. I encourage you to subscribe to it on this page.
The above-quoted issue 4 of the magazine may also be viewed in PDF here.
