bbPress.org

I’ve done some research (and actually got an email from the find-answer owner out of the blue today) and I believe the site/request are unrelated.

But it does prove that it would be a wanted plugin.

Google/Yahoo might not like all the duplicate content however so “noindex” might be a good idea to prevent being search-engine banned.

Another consideration is that I believe bbPress keeps a full index on post text, so the table size for posts would become non-trivial for such a forum.
