eg I moderated a test post. When I click the post-has-been-edited pencil-icon, it takes me to: http://ee-flow.wmflabs.org/w/index.php?title=User_talk:Quiddity&topic[newRevision]=050e89fbf3abf00fc8b1fa163e68c4ac&topic[oldRevision]=050e89fa715ff00fc8b1fa163e68c4ac&workflow=050e88c8a39bf00fc8b1fa163e68c4ac&action=compare-revisions That page should give a summary of the action that took place, if it wasn't a content-edit. (eg. content-moderation, or board-subscription additions, etc)
