Original user request:
Basically we need to be able to mark pages as ‘outdated’ if they haven’t been edited within a certain amount of time. We do not really need the notification, we just need the pages to be ‘marked’ and show a message that there is possibly outdated content.
Once the page is edited, this should of course revert to no longer being outdated and the message on the page should disappear.
Albeit not requested explicitly, the implementation should definitely include the page in the page lists in the notification email.
This would be somewhat similar to using the "archive" label in nature, but it would obviously not archive the page.
