Put you knowledge to good use

You have extensive knowledge on various computer related activities. Say you want to share this knowledge with others... but you can't just write a book about it... you want to make it visual... not just text on paper... you want to make a video clip showing people what to do... and how to do it...

You can take a webcam an record your screen or buy an expensive screen capture software... or you can choose the free alternative with no hassle to it... ScreenToaster. It's a nice website where you can record your desktop activity with the push of a button.
It uses a nice Java Applet that lets you select the source: full desktop, webcam, VNC server... and also some other options like audio on/off and playback speed..
Afterwards you get your video online... easy to share... embeddable videos...
What more can you ask for :)
Go on.. have a try... record your mind... :P
