Be sure to get a match in before July 17th to avoid Freefall. All players who have played a match will move above all players that have not played a match. You can challenge down if you need a match and no one is challenging you. If you have not played a match yet, go and do so. If you get caught in Freefall, you can still come back up in rankings by challenging. The idea behind this is to encourage more play.
This will not a apply to the Women's ladder.
