Comment spam

I'm sorry to have to do this, but I'm restricting comments for a bit. I've had problems with someone posting a bunch of spam in comments, and I'm afraid I can't stop it without locking the comments down a bit. If you're for real, send me an email and I'll assign your login comment rights. In the mean time, I'm going to look at switching the site over to Drupal. Among the attractions there is a bayesian comment scrubber that's supposed to combat exactly the kind of crap I'm running into.
