A bit of a personal appeal here.
My son-in-law, Austin, has Hodgkin's lymphoma. He's 25 years old, which, as it turns out, is the prime age for this to develop. I've gotten rather fond of the kid, and while he's responding very well to treatment, I'd appreciate a good thought or prayer for him.
Another slightly more tangible way to help is to use your computer's spare work cycles to help with Folding@Home, a distributed computing project set up years ago through Stanford University. Distributed Computing takes complex testing and computing and breaks it up into smaller chunks of crunching that any desktop or laptop computer can manage. The concept is fascinating. I have a team set up (#234447) that you can join, but even if you don't, I'd encourage you to look into donating your extra computer power to the cause.
