The ability to insert comments in Word documents is one of the program’s best features.
In multi-user environments, it is an easy and effective way to collaborate and comment on document drafts, without the hassle and waste of paper copies of the document
This is especially convenient when the collaboration is taking place via email. Even single users will find the feature handy, providing the ability to add notes and reminders.
While it is possible to add notes and comments to your documents without using the comments feature, it requires extra vigilance on the part of the user and can become confusing.
Notes inserted using the comments feature, on the other hand, can easily be hidden, deleted, or printed if one desires. Further, when the comments are displayed onscreen, one can easily see the comments simply by scrolling through the document, or by opening the reviewing pane.
