Ah, right you are about the formatting. I've taken your advice and added an "Update release date" link for upcoming items, but unfortunately you will have to wait for the change to be approved before the "Add to my collection" link will appear. I know this is a bit of an inconvenience, but it's an intermediate necessary evil until we do a few other planned back end changes to the way we store the "date purchased" information (null, or "I don't know/care" will soon become a valid option).
Thanks much, Wajo
