Taking the example of donating SpringSource dm Server to Eclipse.org as the Virgo project, this presentation considers the costs and (significant) benefits of such a donation. Improvements to Eclipse.org are suggested. Project leads should glean ideas to apply to their own projects. This file is licensed under the Eclipse Public License.
