As of late, a lot of eclipse.org projects (e.g., BIRT) have approached me about moving to Git after the Indigo release. In preparation for projects moving after the simultaneous release, we’ve setup a Git Task Force.
The task force is simply a group of volunteers that have a lot of experience in migrating to Git and can help your project. To take advantage of this, please sign up on the email@example.com mailing list and feel free to ask questions or join the task force to help other projects. And of course, please checkout the information on the Eclipse wiki on how to migrate.
