There's a couple of good articles on the programming side right here in the articles section, especially this one. Design is another matter entirely; there's of course a large artistic element, but the actual layout and such can't be underestimated. I don't know of any resources in particular for good layout guidelines (well, I know of some, but they're coming up on being a decade old so they aren't worth much [wink] ). Best you can usually do when in doubt is to keep it as simple and clean as possible.

Hey, check theese links out!
