At about the same time the Player's Challenges were introduced, wasn't there also Private Challenges that were introduced at the same time? The Private Challenges were where a player could privately challenge another player (or a select small group of players) of similar skills. That way, a player (or a smaller group of players) with lesser skills (like myself) could challenge a smaller group of players. Sort of like inviting a friend over to your living room to play a friendly game of checkers. I'm not here to compete. I'm just here to do the best that I can (which I admit isn't that good) and have fun doing so.
