Refer a webmaster to Adsense and score $100 when they earn $100. Great deal - until now.
Adsense terms modification: "An AdSense referral is counted when a publisher, who has never previously enrolled in AdSense, creates an account and earns at least $100.00 within 90 days of sign-up. The referred publisher must be eligible for payment to qualify as a successful referral."
