A few days ago I noticed some comment spam and wondered how it managed to get on my website without my e-mail notification system letting me know. Sure enough, it turns out that sometime last December my perl Mail::Sendmail hack stopped working. So I have missed a bunch of comments. I apologize to those folks who were kind enough to comment. I've gone through the comments and put in responses. I'll have to keep checking things manually until my ISP lets me know what the problem is.
