authorSTREAM is a new way to share PowerPoint presentations on the web. authorSTREAM makes it easier to share your PowerPoint slideshows through blogs, websites, on YouTube and even via iPod. You can upload as many Presentations as you want. Once uploaded, you get a unique URL for your presentation and a code to embed your presentation in blog or site. The embedded presentation plays as a Flash slideshow and the viewers do not need to have PowerPoint software.
