I'm not that great with HTML or CSS (although I imagine I'll get better with time), and I'm maintaining this site on my own. Any clever stuff you see, I've probably borrowed it from somewhere. All the messy sadness is my work. (Hopefully the page will hold up!)
PageBreeze - I use this free HTML editor. I find it easy to use and very conveniently free.
Blue Robot Layout Reservoir - I based my two-column layout on the source code available at Blue Robot.
CSS Web Design for Dummies - I use this book as a reference for my CSS editing needs.
CG Textures - Any backgrounds and assorted textures you see in use around here are derived from textures found here. It's a very good resource.
