Sorry - I thought I knew the answer to this one. I've done it & was certain that I'd bookmarked the site. It involved sending an email to the site owner as I recall. Unfortunately, I have several bookmarks that are no longer valid - so I don't know if it was one of those or if I just didn't mark it.
I thought it was a site in another language - like Spanish or Portuguese. Hopefully someone else will have the info for you.
