Are you using Microsoft Word's "Track Changes" or comment features? If you are, help out your fellow users by making sure your comments and changes are correctly identified with you!
When we launch Word for the first time, you're usually prompted to identify your name and initials. But usually when we're doing this we're trying to get something else done and we just accept the default (usually "UTMB"). That's fine, but when 4 people have commented on a document it gets a bit confusing, and it's very easy to change.
To change, go to the Review tab in Microsoft Word, click on the down-arrow for Track Changes, and select Change User Name. Enter your information and click OK. (For illustrated instructions, see Office Online's instructions for changing the user name.)
