Events Starting a new event with all old data removed Go to the Events page and click Add to create a new, empty event. Go to Global Setup / Contacts , click  Show Advanced Options , then click Remove All Customers . Select the access level to delete, starting with Event Administrators . Parents and teachers will then need to log in as new contacts and create new passwords. ⚠️ Important: Only remove contacts before importing your new data — not after. Doing this after importing can delete data you still need. I have two events sharing some of the same teachers — how does blocking/booking work across them? If a teacher is shared across two events, the system prevents double-booking automatically: Booking a slot on one event blocks the corresponding slot on the other event. Blocking a slot on one event also blocks the corresponding slot on the other event. If you need to block time for a teacher on one event only (not the other), use Delete Time Slots instead of the block feature — deleting does not carry across events, while blocking does.
