Can you remember when you first heard about communities of practice? I wish I could. I know I've had Etienne Wenger & Co's book "Cultivating Communities of Practice" on my shelf for a long time. I may have "borrowed" it from my Mum. (Thanks Mum).
The Drupal community working group exists to uphold our code of conduct, and work on the supporting policies and procedures we need to do that. Read more about it in the Governance group on Groups.drupal.org
