[ Here's a bit of irony for you: this was bounced to me by the

Folks, there's really *no* excuse for unsubscribe requests going to
the mailing list.  Majordomo told you when you subscribed what the
proper way to unsubscribe is.  Use it.

Meanwhile, I have just turned on the administrative checks again.  I'd
prefer not to have to, because they occasionally bounce real mail
(including, probably, this), but it doesn't seem like I have much
choice.
