Upload & Sell: On
I was surprised to see it that small too. But the last post on the old thread was Dec 23, 2007, and Jim got this thread started on Dec 27. So we didn't lose anything in the transition.
Given the old thread was just 14 months long, and in 2007 we barely got through 200 pages, it doesn't look like we would have had enough time in the old thread to run 500 pages.
Also, I think that over the years the number of posts per page when up dramatically, and I believe that also affected the older archived threads. We're 20 posts per page now, and that's what I find in MA2A #1.
