Lesson No. 1: posts to Usenet CANNOT be deleted.

But they can be cancelled if the news server permits, so not everyone
gets to read the original.

You'd hafta be VERY FAST.

My response to that above was posted in nano-seconds...

Er, you might THINK you're deleting a posted Usenet message to The
Whole Wide World, but in effect, all you're doing is removing that
posting from "your own news reader", that is, on your own PC.

IF (take note of the command), you unsubscribe from the ... (news
group de jour) and then RE-SUBSCRIBE/RE-JOIN, you'll quickly discover
that any supposed "deleted" messages are, flipping heck, still there
and the world is looking at them.

Absolutely, positively guaranteed.
