Aussi Group for IA (Shop) teachers 80 members and growing
http://groups.msn.com/IndustrialArtsTeachers/
The archives of the Engineering Studies Network are in the group's files section and contain heaps of good information for teachers.
This is a teacher specific group but does not exclude others with an interest in kid's education.
Many of the members are promoting CNC in schools and any input would be welcome
