If you are going to be at NPC 2013, we would love to have you at the un-conference session. It is on 29th (11:30-12:30). We normally pick a few topics and request people to vote for their favorites. As of 5pm on 27th, it looks like this. We will freeze it in 24 hours.
You have a chance to influence it. If you are planning to attend the un-conference session please do vote for your topic.
