"I'm about to cross the line from full-on print designer to (teaching myself) web design. I know basic code but not much else. I plan on getting practice by creating a blog - can anyone fill me in on the most important things I should know? I've heard jQuery a ton of times--and any free tutorial sites that will be helpful in this ridiculously scary endeavor..."This request prompted me to dig around for resources for the self-tutoring designers of the world. Here are links and mini descriptions. I hope this helps.
