Check out the "Teams and Schedule" link on the right and head to the "Schedule" tab in that document to see when the teams are playing each other. Every team plays every other team, with no more than two stand-ins needed in any given game (if everyone has told the truth on their availability survey). Please let your captain know immediately which games you can and cannot make so that they have as much time as possible to arrange stand-ins.

The Challonge brackets link also has when each match occurs in the match details. You can see this by clicking the "brackets" link in the sidebar.
