Good News: I was able to create a site menu using an unordered list with the great help of this column at A List Apart. Right now there’s a whopping two items, but plenty of room for expansion. 
Bad News: IE6 doesn’t like my layout. If you’re looking at the site in IE, you’ll notice that the sidebar is conspicuously hugging the right side of the screen. This is because IE does not correctly interpret a right: 0px; inside of a div with position: relative; margin: 0px 35px;. The reason this sucks is that I want to have a gray line that traces from the menu all the way down to the footer–like it does on the left side of the page. But, since Explorer doesn’t interpret the CSS correctly, the sidebar ends up overlapping any line I try to put over there. Any feedback is appreciated.
Are you sure you can say sucks?
Other than that, I was going to say that I am using IE6 and even though there is no gray line on the right it looks fine. But while I am typing this comment, the gray line that runs at the bottom under the preview, post, etc buttons runs right through the center of your archives box on the right. Out on the main page it is fine though.
