Notes

• The Answer fields have either a gray or white background, depending on whether or not an answer has been previously saved. If you change or erase a saved answer, the background color will not change until you Submit changes again.
• New this year: answers must conform to a specific pattern: one or two groups of (4,6,8,9) digits.
• To remove a previously submitted answer, simply erase just that one answer from this page, and click Submit -- make sure to retain all your other answers. After submitting and refreshing this answer page, what you see is exactly what the judges will see.
• If something goes horribly wrong, send email in place of this answer page submission.
