Article for conference booklet:
Node Access is Drupal's system to determine who can view, edit and delete content on your web site. The authors of Organic Groups and Domain Access will give attendees a guided tour of Drupal's Node Access system, its design patterns, its strengths and its limitations. The session will prepare you to implement your own access control module and prepare us to discuss improvements to the core Node Access system.
