OneDrive (previously known as SkyDrive) is a great way to share your presentations online while you are still working on the slides. When you are collaborating on a presentation with someone else, you want to give and receive feedback without actually editing the slides themselves. To do that, you can use the Comments option that works differently in the OneDrive version of PowerPoint compared to the desktop versions.
