Growing up I learned to use what we have and do the best we can with it. So now comes along Charity Engine which uses computers and current technology where we can all share in productive commercial work while doing good contributing to charity organizations on the other side. 

The leaders of CE thought of putting together a Prize draw. How much more fun can you have computing with a chance to win? The winnings can be put back in to the computing/power resources, your family fund or even given back to charity. 

This makes a lot of sense to me and I have enjoyed the challenge getting it all to work and keeping it running. I encourage you to give it a go as well. Good computing and good luck.
