Enter all of your event's weight classes through the Divisions and Weight Classes form by choosing option '1. Setup Divisions and Weight Classes' from the Event menu. Just select the Weight Classes tab if it is not already selected.
Note that the standard weight classes are provided with Press 4.0 for your convenience.
To add a weight class, press the Add button. The Weight Class Entry dialog will appear.
To delete a weight class, just select the weight class from the list and press the Delete button. Press 4.0 requires you to confirm this request, and it will not allow you to delete a weight class if it is currently assigned to a competitor.
To edit a weight class, just select the weight class from the list and press the Edit button.
Finally, press the Close button to close the form, or just leave it open and go to other features. If other features are already open, you can retrieve those features normally, or you can return to them via the Windows menu option.
