I have just seen this old thread in the "Recent" list, and, as I remember it well and because of curiosity, I have looked at it again. By browsing it, I have noted that as it stands right now, it makes little sense. As I keep a local Primes 1 backup, I have compared both and got a new unpleasant surprise to be added to the list brought by Primes 2: many posts (ten or more) in this thread, by Jacques, Joe, mine, etc, are missing, and the order of some remaining posts is altered.
