Well, my brother-in-law and I were looking at a WordPress migration. Then he was distracted from looking at the CSS issues in Movable Type 4 by the need to put the little one to bed, and while he was doing that, it occurred to me to archive and reload the templates – which got the MT4 CSS working properly, and in turn allowed me to switch to the nice gray layout you see here. Enjoy!
Now I just need to figure out how to get a blogroll going…
