Just now Greg was trying to create an account with shell name 'greg' but we already had a greg. Rather than telling him that he needed a different shell name, it was displaying 'Incorrect or missing confirmation code.' So he kept retyping the capcha and kept getting the same error message and... it was really dumb.
