I have edited the sticky to reflect this:
As well as competing on an individual level, players will also be assigned to one of two teams. All player's scores on each team will contribute to the team score. Teams will have the opportunity to pick a captain before the end of March, and his team points will be doubled, but his individual points will remain the same. Think of the team game as a side game to the individual competition. We will need team names.
Maybe after individual picks end, randomly assign people to one of X teams, depending on the number of people who participate. Create a late team that has some penalties applied for people who put in their picks after the cutoff date and group them all in there.
