Non-profits have their own community site...
Powered by CompuMentor, one of the nation's oldest and largest nonprofit technology assistance agencies, TechSoup.org offers nonprofits a one-stop resource for technology needs by providing free information, resources, and support. In addition to online information and resources, we offer a product philanthropy service called TechSoup Stock. Here, nonprofits can access donated and discounted technology products, generously provided by corporate and nonprofit technology partners.
