To clarify any confusion about deadlines, and the close of submissions: The Deadline for ALL submissions (including task 1, 2, & 3) is now August 16th. For task 2, the initial round enables teams to submit interim solutions, and receive feedback. It is NOT required to submit a solution in this round, but it is recommended as it can improve your solution through feedback. Anyone cal submit challenge solutions in the final round. Thank you all!
