Math Teaching and Pedagogy Stackexchange has passed its first test and is now registering 200 users for a private beta. Anyone can commit at levels from 'Professionals' to 'Enthusiasts' or even 'Just Curious'. As this would be the first education proposal to succeed, the input from experienced members of academia.se from all areas would be helpful.
