Eligible Members may sign up to the competition, to become a Participant. A Participant will be initially assigned to his/her special individual team. If Participants wish, they may form Teams of maximum four members using the "my teams" view in their account, before making any submission. Participants can leave and join Teams freely, under the limit of four members, as long as they, or the Team they would like to join, has not yet made a submission. Once a Team (individual or multiple member) makes a Submission, it becomes immutable. Any Participant can leave a Team, which has not yet made a Submission, on his/her own accord. Joining a Team will require the approval of all existing Team Members.
