Gizmo, the post still exists on my old 'classic' board, the problem was that it got deleted off my new 'threads' board and I wanted to recover it.
As Rick points out; you can't really reimport a thread from the old forums without great difficulty.
So, my yucky solution was to put back my old ultimatebb.* files to stop the redirect. Then fire-up my old classic boards.
After loading up my old boards, I simply opened the *valuable* thread that I needed and used the 'print view' to get all posts displayed. I then used Acrobat's WebCapture feature to capture the thread in PDF … not purdy, but it works; preserving all posts, posters, and date/time stamps .. whew!
I then put back the redirect files and we are good to go again.
Remind me not to mess with the boards late at night when I'm tired. Heh.
