i just received thsi mail: We are writing to share some important information with you about referrals to the AdSense product. As part of ongoing efforts to optimize revenue opportunities for our publishers, we're constantly experimenting with new revenue-enhancing features as well as tweaking those products already available to our publishers. This is the case for referral units directing visitors to sign up for AdSense. After experimenting with this program over the past year, we've concluded that there are other products that are of higher value than this program to publishers in your region. As a result, referral units for the AdSense program will be retired in the coming weeks. Referrals to other products and services remain unaffected. read more here: http://techicorner.com/2008/01/15/adsense-referral-shutting-down/
