Q: I’ve noticed that some people are using a service called “brainshark” for their audio slideshows. Do you have any information about it?

A: You can narrate your PowerPoint presentation easily by signing up for a free account at brainshark.com.

This service is like Adobe presenter, allowing you to add narration to your presentation and then store it in the cloud. Your presentation is always editable and you will have a link that you can put in your emails, websites and blackboard shells. A couple of caveats.... Since your narrated copy of your presentation is stored on their service, you should consider what to do should their service go away.
