This is indeed bizarre I ve not had any reports of this on the Questia side and I ve been checking each one to make sure I did have a lost code once prior but that s to be expected out of the hundreds we ve given out I ll look into this more but I think we can try and cut down on the issue by advocating more use of special purpose e mails for it I advocate brand new e mails for Questia since renewals can not be done The one error I had on my end has not been duplicated since
