If you like to find out how to do stuff, you might like this site called about. com. This link takes you to the first lesson of a free online photoshop tutorial. The lessons can be sent to your email once a week. The first lesson teachs you the menus, the second lesson teaches you the cropping tool, etc. I am on lesson one. My sister just got me the CS2 software for Mac.
(Thanks for sharing the lessons Corrina.)
