I saw several authors reporting this yesterday, but wanted to wait till I got official confirmation before I reported the news. I have received that and have posted it below.
"Amber Quill Press will cease all business operations at midnight (MDT), March 30, 2016 (07:00 UTC, March 31, 2016). The website will be taken down at that time. This means that access to your bookshelf and your Account Profile's Order History will end, as well. Please make certain that you have downloaded all Titles from your bookshelf and/or Order History receipts by that time. Also, be sure you've used all Reward Points you've earned since they will disappear, as well.
If you have any questions or comments, please feel free to contact us at firstname.lastname@example.org.
It has been our pleasure to bring you quality reading material through the books we've sold you over the years. We thank you for your support and loyalty.
