Have you heard about Yugma? It’s a free website that allows collaboration with others through virtual presentations. With Yugma you can give a tutorial remotely as well as provide tech support when you need it by sharing your desktop with others. I first saw this in action when a friend of mine was giving a tutorial on Audacity. She started a conference call in Skype and began a session in Yugma. A link was sent so that we could join in. What a great way to be able to share something from your computer with others! I call that learning when you need it, where you need it.
