How would I get Apple to list a calendar for people to subscribe at apple.com?
It appears that this functionality has been removed.

There used to be a sidebar box with the ability to contact Apple regarding adding your work to any of the download lists on Apple.com. However, this box no longer appears on the page.



Also, the linked page from the old submit link in the box above no longer appears to be functional:


https://adcweb.apple.com/downloads/




This seems to match the fact that no new calendars have been uploaded for years.
