PG--
I thought about that...and clearly, that would seem, on the surface, to be a simple answer.
However, often times I don't re-read a thread that I've read a number of times before...simple because once a thread get several pages, it takes too long to download the page that I want (still wishing for the cable modem.)
I will read a new thread, hoping that something new is suggested...whereas the old threads seem, at some point, like they should be retired to an archive.
