The game listing shown on the home page is just a summary of the upcoming games. What is included in that summary depends on various settings chosen by your organization. If that list of games doesn't include what you wish to see, there are several ways to see additional games.
At the bottom of the summary will be several links that will take you to a variety of lists of games based on your teams/schools role in the game. Additionally, you can use the main menus to navigate to the games page (under Schedules). From there, you can use a "Game Search" form to search for games using a large number of criteria. Additionally, on the games page, you will find a "Quick Links" menu near the upper left. In it you will find a large number of pre-configured searches.
