Re:Last read message
No, 6star, I believe KurtSara is correct. If you click the box to the right of the arrow the browser should position itself at the first new message since the last time you viewed the thread. With two exceptions that I've noticed. One, photos sometimes seem to throw the position off. And two, if you click that box from the front page Latest Roadfood Forum Conversations then, yes, you will land on the last post of the thread.
Actually, there's also a third exception: if you were not logged in when you last viewed the thread, or when you view it the next time, this won't work.
