In step with other open source projects, we recently set up a Google group to act as a developer mailing list.  The Omeka Dev list is open to anyone, but specifically designed to discuss the underlying code of Omeka, plugin development, data and migration, among other things.   Those interested in contributing code patches can do so in this group as well – information about SVN and Trac are posted as a message on the group.  From our end, we’ll use this group as a way to communicate with developers about what we’re working on and changes that are being made.  And don’t forget, for Omeka users who aren’t ready or interested in diving into Omeka’s code, we’d encourage you to continue using the forums which are still “buzzing.”
