So I've mentioned that I wanted to change to a three column layout here. For some reason I thought it was going to be difficult. Before trying to dive in and do it myself, and spending the next several hours cursing css (or, at least, my css abilities), I asked Google one more time. One of the first results was this page, which got me going with no trouble at all. So thanks guys.
Anyway, if you've got strong feelings for or against the current layout, let me know. I don't expect I'll hear from anybody.
