Design in Photo Shop

Does anyone know of a good site to learn how to do design in Photoshop (or any other misc. program of that type)? I don’t mean like colouring a picture in or anything like that, I mean more like the type of thing you’d find in the “Reverance” section of <a href = “”>Ray Of Light</a>. Design, not art.

I know there’s about 4 million of these sites on the internet and that I’ve visited half of them, I just forget where they all are.
