On the fourth Tuesday of each month, we get together to work on projects, ask questions of our fellow Drupalers and have a pint.
These meetups are for ALL levels of Drupal users. Come with your laptop, a project to work on and some questions. We'll learn a bit from each other and get some work done while having a beer!
Check out the official Portland Drupal Users Group site at http://groups.drupal.org/portland. The site has more information about local Drupal meetups, events and opportunities.
