This book was started as the BookSprint project at the 2005 session of WSFII, in London, England (http://www.wsfii.org/). A core team of seven people built the initial outline over the course of the event, presented the results at the conference, and wrote the book over the course of a few months. Throughout the project, the core group has actively solicited contributions and feedback from the wireless networking community. Add your own feedback and updates to the WNDW wiki at http://wiki.wndw.net/.

- Jim Forster has spent his career in software development, mostly working on operating systems and networking in product companies. He has experience with several failed startup companies in Silicon Valley, and one successful one, Cisco Systems. After a lot of product development work there, his more recent activities involve projects and policies for improving Internet access in developing countries. He can be reached at jrforster@mac.com.
- Ian Howard. After flying around the world for seven years as a paratrooper in the Canadian military, Ian Howard decided to trade his gun for a computer.
- After finishing a degree in environmental sciences at the University of Waterloo he wrote in a proposal, "Wireless technology has the opportunity to bridge the digital divide. Poor nations, who do not have the infrastructure for interconnectivity as we do, will now be able to create a wireless infrastructure." As a reward, Geekcorps sent him to Mali as the Geekcorps Mali Program Manager, where he led a team equipping radio stations with wireless interconnections and designed content sharing systems. He is now a consultant on various Geekcorps programs.

About the solar power guide
The source material for the Solar Power chapter was translated and developed by Alberto Escudero-Pascual. In 1998, the organization Engineering without Borders (Spanish Federation) published the first version of a handbook titled "Manual de Energía Solar Fotovoltaica y Cooperación al Desarrollo". The handbook was written and published by members of the NGO and experts of the Institute of Energy Solar of the Polytechnical University of Madrid. By curiosities of life, none of the members of the editorial team kept the document in electronic format and more editions were never made. They have passed almost ten years from that very first edition and this document is an effort to rescue and to extend the handbook.
As part of this rescue operation Alberto would like to thank the coordinators of the first original edition and his mentors in his years at University: Miguel Ángel Eguido Aguilera, Mercedes Montero Bartolomé y Julio Amador. This new work is licensed under Creative Commons Attribution-ShareAlike 3.0. We hope that this material becomes a new departure point for new editions including new contributions by the community.
This second and extended edition of the solar power guide has received valuable input from Frédéric Renet and Louise Berthilson.
Special thanks
The core team would like to thank the organizers of WSFII for providing the space, support, and occasional bandwidth that served as the incubator for this project. We would especially like to thank community networkers everywhere, who devote so much of their time and energy towards fulfilling the promise of the global Internet. Without you, community networks could not exist.
