change in comments

After discovering some spam in the comments, I've enabled word verification. Sorry about the extra step, but hopefully it will prevent me from having to disallow anonymous comments.

I don't spam-hunt every day, so if you see spam in any of the comments, PLEASE E-MAIL ME at grey_nereid ~at~ yahoo ~dot~ com and let me know which entry you saw it in so I can delete it and take further security measures. Thanks!
