11 people showed up and at least 11 issues were worked on. This event is easily repeatable. All you have to do is:

1. Be in a major city. Know the local developers or get it posted on the front page of Drupal.org.
2. Say you will be somewhere for a few hours and tell people to drop in whenever they can.
3. Bonus step: figure out some way to pay for coffee. It isn't too expensive.

This gets people out of their office and in a space where they can concentrate on working on issues and get help from others.

We used a local coffee shop so the space didn't cost anything. If you set up one of these events do make sure the owners are okay with it and make sure your group is buying enough things and not simply leaching off the free power and wireless. This will help make you welcome to return.

Things started off a bit bumpy since the wireless was down when I arrived. Luckily it was up by the time the second person arrived. A wiki page was used to keep track of what happened. I'm guessing there are more issues we worked on which did not get recoded. My attitude towards the wiki was that it should be a place for listing what gets done and should not be a part of the actual working process since editing the wiki is another step which gets in the way of productivity.
