I view "List By Thread" exclusively. So, I never realized, until today, that I am unaware of messages moving through SMTnet on "List By Message" that don't shw-up on "List By Thread." For "List By Threaders" these messages are totally unseen.
These "List By Message" people post to previous threads, sometimes six months old, but these messages are invisiable to the "List By Thread" only folk, because recently posted messages are attached to threads that rolled-off the screen months ago. Wierd. Orzit weird??
