MsgBox 'No track-changes in your selection!', _ Please let me know if you see this and it works. Here's my code, which I unfortunately can't test as my work PC has authors locked as a security policy. I think I have a solution, which conceptually works by taking all revisions with a specific author, storing them in collections, rejecting them in the body of the selection, changing username, then re-implementing the changes as new amendments to the document (thus creating new revisions with the new author). I am a near-complete novice at coding of any sort but a pretty quick/intuitive study and I've been hacking away at this problem as one of my first projects. NOTE: This is a very old question but this seems to come up A LOT from googling and no-one has provided a solution here or anywhere else, so I am adding mine.
