Believe me, I hate to do this, but until I can find a better solution, I've made the comments section unresponsive to html. The idea is that if the spammers can't link, spamming won't be useful. I wouldn't bother, but I'm getting so many porn-oriented google hits now that I've got to do something. Comments will work fine, and you can link (just copy in the url), but they'll be less pretty. Apologies all around.
