I just go the first unread post and then when I get to the first post of the game board I click it. It will say what round we are on, and if I haven't picked, I will pick from the section that is partially filled. If I'm too far behind, I will just start where everybody else is and go from there.
Frankly, the round posted on the game board is not always reliable. We forget to update that too often. You are better off going to the last page and working backwards.
