You can do any of the challenges that Meghan lists on the
challenge tracker for points in September.
Any challenge that comes out with less than a full week on it before the end of the month (the ones below the line near on the tracker) can be used for either August or September.
A new release is anything released on saturday up until the following friday and they can be used on any of the challenges on the current tracker. Not all the challenges are eligible for double points (52 Card Pickup is one that only gets 1 point regardless of whether you use a new release or not)
Does that help at all? Hugs Crystal xx
