The Breast Cancer site is having trouble getting enough people to click on their site daily to meet their quota of donating at least one free mammogram a day to an underprivileged woman. It takes less than a minute to go to their site and click on "donating a mammogram" for free (pink window in the middle).
This doesn't cost you a thing. Their corporate sponsors/advertisers use the number of daily visits to donate mammogram in exchange for advertising.
Here's the web site!
http://www.thebreastcancersite.com/ They have links to other sites with the same deal on there, too. While you're at it, you can buy rainforest land, Feed the Animals and Feed the Hungry.
