History of editing a record
is it just who edited it last? Or the history of all who edited it? If it is the last, the bottom of the page of a record by default should say who created it first (owned) and who edited it last (modified). But, if you, as an admin, edited some functionality on the back-end of the app, it might take your name as the last person to have edited it on all records in the app. Hope this helps.
