I would like to moderate WordPress users’ edits to their own profiles. As I understand it, the default would be for the profile changes to go online immediately. Instead, I’d like to leave the older version online, until an Admin has approved the edit.

I've checked several of the moderation plugins (e.g. Revisionary), and the user directory plugins, but they only seem to moderate the creation of users, not their revision.

How could the revisions be moderated?
