When I click on the latest post of any thread, I should be taken directly to the last page of that thread and not to the first page. The reason I click on the latest post is that I have already read the previous posts in that thread.
Clicking on the orange down arrow to the left of the thread should take you to the first unread post. You must be logged in for this to work. If you click on the orange right arrow at the far right next to the name of the last poster you will be taken directly to the last post in a thread.
