First this board works well, unlike some I have used...
I use the unread button. Sometimes it works, sometimes it doesn't. If I get nothing using the unread button, then I try:
No unread topics found since your last visit. Click here to try all unread topics.
WHat I would really like to see is once you click unread and all the threads are shown, I would like a box next to each topic that I could select and individually mark threads unread.
If I want to clear out my unreads, then I have to look at each topic, or click mark all as read.
My $.02 on the board.
