I have Word 2011 and registered my name as "User" since I don't like my name automatically being appended to the Properties section of every file I create. When I use Track Changes, though, the name logically shows up as "User" and it gets confusing for classmates and colleagues who want to know who that is (which happens frequently want many people edit a document using Track Changes). Can I change the name that shows up with Track Changes without re-registering Office itself? Googling the question finds lots of answers that successfully explain how to do it in Office for Windows but I haven't been able to find anything in Office for Mac. Thanks!
