Photoshop Elements Help Manual

As I begin to learn the details of Photoshop Elements 6 for Mac, I am using this manual by Barbara Brundage, as a guide.

I like the book because I can read from front to back, but also, since I'm trying to get pictures on the blog now, skip sections to learn what I need to know today.

Do you have any favorite sites or manuals for Photoshop help? Leave a comment to share the information. Thanks !
