At any particular time, I am interested in a number of different threads in various forums. It would be nice to have a feature that would allow you to add a topic to your watch list and have it automatically flagged whenever there is a new (unread) post to that topic. Here is the rationale. In the last few days, I made a dozen or so posts in 6 different forums, and to check on the progress of those threads, I am forced to go to each of these 6 forums and remember in which topics I posted, and do it all over again if I need to see the progress. This is just a waste of time.
Yes, this is a much-requested feature and a high priority for any new posting software we implement here. (It's way too much trouble to hach it into UBB I think.) Progress is being made in this area, but no promises yet.
