I've got a problem and can't figure a way around it.
If I don't or can't, due to interuptions, read the threads quickly enough they are suddenly all flagged as read and the "last Unread post" button disappears.
The question is how can I get this timer extended or turned off all together. I like to read all the posts and don't want them flagged as read until I can actually read them.
Also if I exit the Bulletin Board all unread threads are marked as read when I return.
