You may enter scores in one of two places: on the team's schedule display on the Teams Page, or on the Games Page. When a team's score shows a small "dot" or a question mark, you may enter a score. Dots appear on game day and question marks appear for dates in the past.
When you click on a "dot" or question mark, a small "Enter Scores" dialog appears for you to enter the scores. If you ever need to modify a score, double-click a score to bring up the dialog again.
