During the next week, the Worldchanging offices will be closed for a little summer R&R. During the break, we'll be running a "Worldchanging Retro" series, pulling the best of the archives from the past year and presenting them anew.

For seasoned readers, we hope you'll enjoy the chance to reconsider some ideas in a new context and with fresh perspective; and if you're new to the site, consider this a high-speed overview of some of the highlights you may have missed the first time around. We'll begin mid-2005 and move towards the present, with a day dedicated to Katrina/Rita and disaster relief.

So kick back in your hammock (within range of the wifi signal) and enjoy. Happy summer...
