Working with more than one author or reviewer: Who did what?
Tip: Terminology trap! Once upon a time, Microsoft invented “Track Changes”. “Authors” put “changes” into their documents. More recently, “Reviewers” make “revisions” to their documents. And “revisions” are one kind of “markup”. So, in Word 2002 and 2003, you display the work of a “Reviewer”, but you may do so by choosing the colour “By Author”.
