The Drupal Ladder project is open to contributions and collaboration from anyone. To help coordinate and mentor contributor's activity, the folks who were most active on the project have formed a steering group that will meet consistently each week to report on progress and keep the momentum going. The steering group helps distribute effort in 5 main areas, with mentors assigned to each area.
More information about the steering group coming soon. You can talk to the group at http://groups.drupal.org/drupal-ladder
