sorry to have to do this

I've had to add a word- verification step to the commenting process, so if you decide to comment, you'll have to type in one of those funky-looking words that proves you're not a machine, or an alien, or something.

I had to add this step because people (or perhaps machines) were spamming my comment box. Can you believe it? Some people (or perhaps machines made by people) have no class at all.
