From the main page of your convention there should be a button that says "Registration / Events / Merchandise". You will need to be logged in to the platform to register for a convention. Click on this button and the events will be displayed on the product page. Add the event you want to attend to the shopping cart. For some conventions this may be a Zoom Event with a $0 cost. This allows the convention to get a estimation of the number of attendees for the events. After you have entered the events and products to the shopping cart you can proceed to checkout to complete the registration.
