Free Screencast Tool

I know about a tool which is completely online and can help you create screencasts and it is totally free. The name of it is Screentoaster [http://www.screentoaster.com/] and with it you can create tutorials, lectures that can be embeded to any web site or can be uploaded to youtube. One disadvantage is that you cannot edit your records but you can do it with a tool called Any Video Converter Professional.
