unsubscribe instructions don't work

["Richard" <richard@example.com>]

It always annoys me when people send "please unsubscribe me" messages to a 
mailing list, but the instructions given don't work. I apologize for being 
too lazy to track down the person in charge.

The list owner's address doesn't work either.

This list appears to be the stomping grounds of a close knit group of high 
level users. That's fine, but I don't fit that description and I feel as if 
I'm intruding here.
