There is now a specific course for discussing and contributing to the development of Moodle certification.
It's under Community Discussion (in English), and called, rather unimaginatively and unsurprisingly(!) Moodle Certification
Please feel free to join and help shape the future of the Certified Moodle Tutor scheme
We will probably move this discussion into that course, but it will remain here for the moment as a 'pointer'
