Adobe Creative Suite 3 Video Workshop are the best free video tutorials. This is great way to learn new skills and learn more about Adobe products. Each video takes about 3 to 5 minutes. You’ll learn tasks, tips, and tricks from leading designers, developers, and Adobe experts. You can find out more information about the instructors in the “Detail” panel and give your feedback as well.

I don’t have Adobe CS3 right now, hopefully in couple of weeks later :)
