September is Childhood Cancer Awareness Month. From his article on 512 Pixels:
I've set up a St. Jude fundraising page that I will be linking to instead of RSS sponsors for the month of September. My goal is to raise $1,000 for the kids of St. Jude this month It takes $2 million a day to run the hospital and research center, so $1,000 is a drop in the bucket. Let's make it our drop.
This is an important cause. I’ve already donated, and you should too.
