This week I happened to try to change the email address on my account, but then found that no AutoPuzzles emails were being sent. Thus, I couldn't receive the activation email needed for the different email address, and I was locked out of my account.
Thankfully, I was able to contact someone by email who could help with this, but I might well have not been able to.
If anything like this happens to anyone in the future, what should they do? The AP website doesn't seem to have any options for contacting anyone without actually being logged in.
