I want to purchase a group registration but don’t know who is going to participate yet

No problem! When purchasing a 5, 10 or 20 pack of seats you will be able to skip entering registrants during the checkout process. You will receive a receipt with a link that you can use to add attendees at any time up to the purchased amount. You can also remove attendees if someone has a conflict and can not attend. Changes may be made at any point up to the day of the training.
