I posted about Open Source Sustainability a few months ago, so I was pleased to read about an upcoming event:

We are gathering together a large community of like-minded groups and people, called the Open Sustainability Network (OSN), to work on overcoming barriers to openness and collaboration. Our first conference will be at San Francisco State University on October, 18th-19th and admission is free.
