It doesn't take a lot of skill. I haven't had any teaching on any of these programs. I just got photoshop and I have only been using it for about a week. The best way to learn is just to try different things out, see what looks good. A good sense of design is all you really need. Most of the early sigs I did were real easy, it's mostly just finding a few pics and putting them together in a way that looks good.
