There should be two levels of permissions (besides whatever one can see on the public view):

1. Game creators: can create a new game (and add players if they aren't already in the app)
2. Admins: can edit games, edit players, see leaderboards, etc.

Maybe make it configurable? Maybe all these settings should be configurable, like points per game and games per match?

This was Mark's brilliant idea to only have the leaderboard visible like one day a month or something (the value could be configurable). We probably don't have to do it for all stats, since some are purely informational. Also, admins (people who can log in) should be able to always see the latest leaderboards.
