I've been working non-stop for the last several weeks to prepare my images for submission. I went used the link in the email I received to go to the page to upload and received the message, "Certification Closed." I returned to the list of dates and discovered that the deadline fell at noon, not midnight as I had thought. It's a tough lesson to have to wait another 2 months after so much work, but there it is. Ughhh!
