Screencasting in 7 Minutes
Betsy Weber over on the TechSmith Visual Lounge shared some good information from Ian Ozsvald about screencasting tips as well as some sample screencasts.
My favorite tip is, "Just Do It - don't worry about it, just make a recording and repeat it if it wasn't good enough. Soon you'll have something online that does the job." Jing is a good way to practice and start screencasting. It's free, doesn't have a lot of complex features, and makes it easy to get a screencast on the web for others to see.

Hi can someout out there send me a sample of what they screencast.
Hi Tina,
Good point. I should have included a link to a wide variety of example screencasts. Check this out: http://visuallounge.techsmith.com/screencast_of_the_week/
Besty also just posted about a resource called Scrast that has more tips and resources. http://visuallounge.techsmith.com/2009/09/all_about_screencasting_-_meet.html
Hope that helps!
