I noticed a new “Referral” tab when I check my Adsense earning today. Google Adsense is offering USD100 for each referral you made, with the condition that the person you refer must have made it to his first USD100. There’s a number of different banner size for it. Log in to your Adsense account now to check about it. You might want to add a banner to your site.
If you are not a member yet, I’ll be glad if you would go there with my banner below, and register yourself.
