Site changes complete
Sorry for the burst of index posts for those of you reading via RSS aggregators. The site changes are done now; there's a menu in the sidebar linking to the topic indices, and I've added a couple of links to the (still too small) blogroll. I might still make a polish change or two to the site, but nothing that should trigger any new RSS updates. Please let me know if you happen to notice any problems with the indices or sidebar.
