When joining the Correspondence Game waiting list, you now have the option to leave yourself on the list indefinitely to allow for multiple game pairings. In other words, when you put yourself on the corr game waiting list and then get chosen by your opponent, your game pairs but you do not get removed from the list. When you have started as many games as you want, you can manually remove yourself from the list.
 
We will be extending this functionality in the future to allow you to specify exactly how many games to start before you are automatically removed from the list, as well as set an absolute number of active corr games so if you fall below that number you are automatically placed on the waiting list.
