To proceed to the checkout, you need to create an account with CE21 or have a pre-existing account. This is essential for registering for your chosen event. If you're registering multiple people, some of whom might not have accounts yet, begin by creating your own account and selecting "assign later." This allows you to add them as attendees to your group through your purchase history at a later date.
NOTE: If you're a TNA member, make sure to create your account using the email associated with your TNA membership.
