Hi
It's not very important but i thought i would put the suggestion out there. On the board index screen, perhaps it would be better to show a board listed as having new posts only since the last time it was visited rather than if there are simply unread posts. As of now, the only way a board would show no new posts is if you literally read through all the thousands of topics there. Is this at all possible. Please just ignore this if not.

There's a link in the lower left that says "mark all forums read".
Check for new posts then mark everything read. That's what I do.
