Mr D, you may wish to read this:
http://docs.yahoo.com/info/copyright/copyright.html
This comes from the copyright policy link on geocities.yahoo.com.
Yahoo is pretty clear with its copyright issues. I suggest that if you were
to email them a link to your site and a link to bullis's site they would
immediately take the latter down.
Yahoo has also developed a good reputation in their handling of
copyright claims. Many a Yahoo Group or GeoCities was deleted without
question if the copyright-holding party presented sound evidence of
the other person copying their work.
A copy of Richard's post sharing his admission would also help
support Duende's claims as it would show Yahoo that Duende did ask for
the content to be removed. And Richard basically admitting,
publically, it did come from Duende's site.
Trivia: Don''t send attachments to Yahoo - those emails won't be
opened. If you get an auto-generated email for some reason then
respond to that restating essentially what you already wrote [without
deleting any of the quoted portions] and offer to send them any
attachments needed for comparison on their side.
