"As a Curator, I want to get a list of all changes to pages in the project, so I can review the current versions of pages in the project."

This is different but probably has the same upshot as an administrative user story:

"As an Administrator, I want to get a list of all changes to pages in the project, so I can detect if there has been any bad behaviour lately."

If we see a lot of daylight between them, we can split that second one into a separate user story.
