As you can probably tell, I've changed the way the pages look. You can (almost) change the style back, if you want to, by using the Style Chooser in Mozilla or Opera. If you use IE, you can just live with the change. :)
Update: The content columns used to be fixed width, meaning that if your browser wasn't sized exactly like mine it would look weird. I've since updated and changed it so that the content column flows to fill up the space and the sidebars take up less room.
I've also moved the "welcome" post over to the sidebar.
