As part of publicizing my new Essential Earthbag Construction book I spent some time answering questions about earthbag building in general at www.permies.com where they gave away several copies of the book to those who participated. As I spent more time at this site I realized that it is one of the most informative and valuable forums I have ever seen. It is enormously popular with permaculture enthusiasts from around the world. Topics covered include: gardening, farming, building, homesteading, energy, life styles, community, wilderness, resources, education, artisans and publishing. In other words, they cover a lot of the same topics that we do here at Natural Building Blog, so you might check them out. The folks who hang out on this forum are very knowledgeable and helpful.
