I've just discovered this organisation called "Woodcraft Folk" through Twitter, their bio on Twitter read: Empowering children and young people to influence the world around them, starting with education about equality, internationalism, environment and cooperation.
Just checked out their website and really liked the sound of their ethos: http://www.woodcraft.org.uk/about
Only just discovered them myself but I was just wondering if anyone out there has had any experience with them, participating or volunteering etc?
