Login and Click on New Tournament. If you are starting a completely new event, enter in the details and click on "Create New Event".
If you wish to copy over an existing event, click on "Copy Event" in the top right corner. From here you can select which event you would like to copy. This will move over all of the details from your previous event so you do not have to start from scratch.
IMPORTANT: You will always be able to access information from your previous events so you can download past player and sponsor lists. All of your events will be listed when you first login and can be found in the "Organizer Dashboard".
