If you collaborate with others to create presentations, PowerPoint offers several useful features to help you and your colleagues edit presentation materials. Your presentation can be viewed by multiple reviewers, and PowerPoint tracks feedback offered by each person. You can then combine all the review documents into a finished slide show.
You can also use comments to add notes about slide elements and text. Comments are helpful when you want to insert reminders to yourself about checking a fact or adding an explanation about a slide element. Users who review your presentation can also use the Comment feature to add comments to your slides.
You can share your presentation with others via email or as a Web page. For example, if the person you want to view a presentation does not have PowerPoint installed, you can save your slide show on a Web page and allow them to view it in a Web browser.
