Is posting in a newsgroup spam? I understood ebay policy to be that one
can't advertise within an auction and direct people to another site
which I don't do. I don't believe there's any policy against directing
people to an ebay auction. I didn't know about the FS and I will follow
the rules. I know there's no room for error when one is learning new
things on the internet and no forgiveness either.

If it's possible to report the posting to have it removed I will do it
myself.
