Is it possible to use revisions with Frontend Submission?
Currently, I allow authors to edit their own posts using the frontend submission form (the post data is saved in custom fields). I would like to allow other users to suggest edits on posts that are not theirs, and when they submit it, it should be in a pending state until it is approved by either the original author or an editor. I need to keep track of the revisions and also display them on the frontend (with the highlighted differences). I also need to keep track of which user submitted each revision.
Are there any hooks that will allow me to do this?
