Screenr is a free, web-based screen recorder that let's you easily make a screen cast recording of what you are doing on your computer. This is a great way to create tutorials, lessons, and more. It is completely web based so there is no software to download (it runs using Java).
You can create your own account or sign in with your Twitter, Facebook, Google or Yahoo account.
You simply click the record button, it then loads the recorder. Hit record and it gives you a countdown "3-2-1-Go!" and then starts recording. You can make recordings of up to 5 min long. The recordings can be embedded in blogs and sites too.
This is an easy way to create a screen cast to share with others.
