If you submitted your payment information during checkout, your payment will go through when the Event Organizer approves your order. That way, you won't pay for an event you aren't approved to attend! Until then, an authorization will be placed on your account.
If you sent a check payment, please allow the organizers some time to process the payment and mark the payment as received on EventHub. To verify that they have received your check, you can message them directly.
