By links I meant internal forum links, ie when you are directed to ANOTHER thread in the forum as part of the argument, as in: GO HERE
When Andy imported the old forum, the software assigned a new unique identifier to every page of the old forum. Consequently, the old links are all dead. I doubt that he can fix that, and you will have to spend time searching by hand now.
I have fixed one or two of my recent threads, but it would perhaps be a good idea if others did that for their own threads (If they can find them).
