Plague of Spam

I've been getting drowned in comment spam. So, until I get a better spam solution, I've disabled comments for unregistered folk. For the time being, you'll need to login with TypeKey. (Go here to register, if you haven't. It's free). I like to keep my comments as open as possible, so sorry about this. But TypeKey is pretty easy.
