authorSTREAM, a site that lets you upload and share your PowerPoint presentations upped the ante today by offering a slew of new options:
Download original presentations: You can now download the original PowerPoint presentation (or other file) if the author of the content enables the relevant option (see figure below).
Share on YouTube: You can also share your presentations on YouTube. This option is now available for presentations that include narration or rehearsed timings — these presentations would automatically be available in a video format (MP4) that you can upload and share on YouTube.
Share on iPods: Again this option is only available for presentations that include narration or rehearsed timings.
