This is how I tend to read the BBS:
Open a separate window for each forum with new messages.
For the n (pretend n< 10 or so in this case for simiplicity) new/updated threads show in a forum, create n copies of the forum thread list (using ctrl-n), then click one thread with new messages in each window. [I do this rather than right-click new window on each topic in the original forum window, since IE seems unable to scroll to the achor point when I do it this way. Work computer, so I can't use another browser.]
Sometimes, not always, when making the new windows for the threads, the new windows will suddenly mark all threads in that forum as already read, making hunting for the beginning of the new posts difficult. Haven't found the reason.
Anyone else have a better technique?
