You have all probably noticed that there is now the title of the most recent post in each forum on the home page.
I want to explain how it works.
Clicking on the title of the most recent post will bring you to the most recent unread post in that topic. If you have already read every post in that topic, it will simply bring to to the first page of the topic.
If you click on the little post image following the author of the most recent post, that will take you to the most recent post in that topic.
