I'm trying to create a master-list of charities that gamers, geeks and tech nerds are especially fond of.

Child's Play and Extra Life are obvious ones, but I'm interested in hearing about what else is out there. Anyone who could link me to some other efforts from within the gamer community would be much appreciated.

Thanks guys!

List in progress:

Child's Play: A game industry charity dedicated to improving the lives of children with toys and games in our network of over 60 hospitals worldwide.

Extra Life: An annual 24-hour video game marathon that raises money to help kids at Children's Miracle Network Hospitals.

Hero Initiative: The Hero Initiative creates a financial safety net for comic creators who may need emergency medical aid, financial support for essentials of life, and an avenue back into paying work.

Heroes 4 Heroes: Working directly with members of the United States Military, corporations, and the general public to provide portable media to active troops in order to boost morale and keep men and women in uniform culturally tuned-in.
