The Mellon Foundation will for the first time "recognize not-for-profit organizations that are making substantial contributions of their own resources toward the development of open source software and the fostering of collaborative communities to sustain open source development." (Mellon.org) Multiple awards will be given at each level: $25,000 and $100,000 depending on the significance and benefits of the project.
"To nominate an organization for an award, please click here. Each nomination must address one organization and one software project. You may nominate more than one organization, or nominate the same organization for more than one project, but each organization/project pairing must be a separate nomination. You may nominate your own organization or project." (Mellon.org)
This is a great way to recognize an open source project!
