What happened in this thread:
Back and forth question/answer like usual, then suddenly a bunch of posts removed, and the thread locked? No explanation? No link to new location if it was moved? Can't seem to find it anywhere ...
Your link appears to be to an ancient long-abandoned thread from 2005.
If there were recent entries, then they were likely to have been some sort of resurrection hijack postings, and it seems they were likely taken away from that thread. (I do not know where they might be, branched away or removed.)
If you happened to be the person that resurrected it, then start your inquiry fresh.
If you were responding to someone, then we can hope they realize they need to post their own inquiries fresh.
That will be the better way to get a topic discussed.
I can't speak to that specific discussion (will assume a mod started a new branch or removed something inappropriate), but we are enabling automatic locking for posts over a certain age (4 months, I think) to prevent resurrections of ancient threads where a new thread would be more appropriate.
