Screenr is completely free and allows you to record screencasts in seconds. Simply click the record button, set your recording area, and you're on your way. Sreenr is web-based so there is nothing to download. You can record on a Windows computer or a Mac. The screencasts play everywhere on the web, even on an iPhone. Be sure to watch the Screenr tour on their home page.

Once your recording is finished, you can download it as an mp4 file, share the URL, embed it, and share it directly to YouTube or Twitter.
