METAPOST: Commenting

I've unfortunately gotten hit with a spate of comment spam, which is when some automated computer system posts a "comment" on your blog that's actually an advertisement for some product. To keep from having to delete all of those, I have turned on the feature that says you have to be a registered user to leave a comment.

We'll try that for a bit and see how it works. My apologies for any frustrations this may cause.

UPDATE: That didn't work. So, now I've turned on word authentication. Hopefully that'll do it.
