People who attend the Riverside ultimate pickup game can use this page to decide whether the game is on, when it's not clear there will be enough people for a game. A day or half-day before the game, someone suggests (via email, facebook, or whatever) using the page. Then people who want to play enter their names (and the names of others they know would come) here (or on Twitter in a tweet that mentions @). An hour or so before the game, whoever asked people to use the page decides whether there is enough interest for a game and posts their decision here.
