Key Points
You can insert comments in a presentation and then view them in the Revisions task pane.
You can set a password that must be entered before someone can modify a presentation. If you want others to be able to read or copy the presentation but not make changes to it, you can also set a password that must be entered before someone can open the presentation.
You can quickly send a presentation to another person for review by using e-mail.
You can merge different versions of a presentation into the original and then review revisions and comments all in one place. You can use the buttons on the Reviewing toolbar to view, accept, and reject revisions.
PowerPoint uses a different color to identify the comments and changes made by different reviewers, so you can review all comments and changes at once or work with those of each reviewer separately.
