All right -- in light of some recent goings-on in my comments, I think I'm going to have to create a comments policy here. Three basic rules:

1) You will have to put a real email address in the email box. I'm not going to test every single person who comments, but if you're being obnoxious and you're using a fake email, you smell a lot like a troll.

2) No sock-puppetry. I can see your IP address, so I'll know. I caught one person doing this on my Blogspot blog, so I do check.

3) No name-calling or obscene language. I reserve the right to delete any posts that do so.

I'm not going to delete any comments made before this announcement, but from now on, consider it in force.
