But each new post brings the thread it is in to the top! And each new post pushes something else down. If the new posts are to remain with the threads, I can't see any other way to do it. (If you use Agent to read newsgroups, you know that they have spent 3 years writing a VERY complex program that allows you to customize how the threads of articles are displayed-by date, author,subject, reverse order, etc..) I doubt Mudcat/Digitrad is about to do anything like THAT soon!
If you use Netscape in here, you can at least use the feature that lets you specify a color change to threads you have read....it tells you whether there have been any new postings since you last checked.
