By default, Acrobat versions 7 and 8 label your PDF comments with your login username, which may not have any resemblance to your real name. During a review involving several reviewers, this can make it difficult to figure out who made certain comments in a PDF.
Not only it is not obvious how to set the default identity, the preference that should make it happen doesn’t. But with a few trips to different areas of Acrobat, it can eventually be done.
To set your default comment identity:
1. Open the Preferences dialog box in Acrobat and go to the Identity panel.
2. Make sure the Name represents the name you want to use to label your comments.
3. Go to the Commenting panel in the Preferences dialog box.
4. Under Making Comments, make sure “Always use Log-in name for Author name” is disabled.
5. Click OK to close the Preferences dialog box.
6. Select any commenting tool, such as the Note tool, and add a comment. It doesn’t have to be anything important, because you can delete it after you’ve completed this procedure.
7. Right-click the comment and choose Properties. (This step seems to work only if the comment’s window is closed on the page.)
8. Click General and make sure the Author name is the name you want to use to label all of your comments, and click Close.
9. Right-click the comment and choose Make Current Properties Default.
That should do it. While it would seem that steps 2 and 4 should get the job done, the entire reason this procedure is necessary is that Step 4 never seems to work on its own.
