Consider this a substitute for my suggestion #2 which I posted back at 26-Sep-00 - 11:23 PM:

Right now, when somebody decides that a thread is too long, they start a new thread, and create links to link them together. What I'd like to do is AUTOMATE that process. Make a new thread appear automatically when the old thread reaches a certain length. Set up the links automatically, and use a standard format (size, font, color, position, whatever) that is easy to recognize. Once the new thread is started, make it impossible for anyone to post to the old thread. The new thread could even have the same name as the old thread; you could distinguish them by the date/time they were last posted. How's that?
