cybereality It appears that old forum links are not redirected to the new threads. This is not a high priority, but it's fixable. I had to do that once for a PHPBB forum, let me know if you need help with that as well.
Coming from a search engine looking for answers, it gives the impression that the forum is offline/dead. The only reason I know to go to the front page and copy-paste the thread title into a forum search is because I'm aware of what happened here.
The first day I was clicking on broken links, I thought the forum was temporarily down again. All those search engine results have the resemblance of being inaccessible and lost.
EDIT: Fixed the quote. This new software is overwhelmingly modern for me to navigate comfortably.
