How do I create my playoffs after my season is complete?

You can create a postseason league by using the League menu and Create New League feature. Once you have created a new postseason league, you can copy your playoff teams from your regular league into it by using the drag and drop functionality of your mouse. The main program screen uses the drag-and-drop functionality of your mouse. To copy a player or team from one league to another select the player or team with your mouse, hold the button down and drag to the league you wish to copy them to on your league list.
