Half way through the Challenge...and although an incredible amount of work has been accomplished, the numbers have the upper hand right now. 13020 WU's have been completed but 16036 remain. Our goal is still to reach n=5M. Therefore, we are hosting a sprint this weekend to see if we can get back even or maybe ahead of where we need to be in order to reach 5M by the end of 31 May. For more information, please see this forum post.
