This message was spammed across loads of listservers - I know the
world.std.com ones (including rocks-and-fossils which I'm also on) were hit.
This anonymous person does not subscribe to these groups, and so they
will not see your message. The rocks-and-fossils sys-admin suggests
spamming the anon address from where the message came from.
Unfortunately this about the best we can do. (I haven't, because I
deleted the message as soon as it arrived).
Its a price we have to pay for freedom of speech and all that jazz!
