John, part of the problem seems to to be that the Renderosity admins have changed their de facto policy, without bothering to ask anyone if they do have permission to distribute the material. They possibly don't have a procedure to deal with snail mail. And, incidentally, be careful about such terms as "notarized" -- in some countries a notary is a very rare and expensive sort of lawyer, while in the US a notary may be a relatively junior member of office staff.
