For the past couple weeks there has been a long discussion thread happening on the Net Tuesday San Francisco Meetup list serv about people wanting to form a Drupal for Good group in the Bay Area.
Joshua Wiese set up a Drupal for Good San Francisco Bay Area Google group to help get it organized. You can join the group by clicking here, and anyone can view any of the group's activity, without joining, by clicking here.
Not in the Bay Area? Here is a link to the Drupal for Good discussion group that anyone can join wherever they live. You also might want to check out the Drupal Dojo.
