This page contains the entire collection of my screencasts to date.
Many of them are in SERIOUS need of re-doing!!

Thanks for visiting!

I recommend that you SAVE THEM TO YOUR HARD DRIVE
and then view them from your computer!

The 2008 Screencasts are flash files and don't need to be saved to your hard drive. They will play automatically upon opening. Also, the noise problems are eliminated by listening to the file with earphones. Apparently the base bounce isn't a problem through the earphones. I'm still learning how to best record. Sorry.
