How to make a quick and easy screen recording without installing software...

I found a tool called Screenr that allows you to create quick screencasts and publish them directly to YouTube or download and edit them. The catch is that they can only be 5 minutes per screencast, so longer videos will have to done in parts. If you'd like to see an example of what the product might look like, see my blog post How to record directly to YouTube using your webcam or watch it in HD.
