If an attendee is signing up via LinkedIn, we can collect their name and email addresses from the event page on LinkedIn. We would use the attendee list to estimate how many attendees might show up on the day of the event. We might also email them the Zoom link to the event. When we conceptualise the next season, we would send them an email with the concept note and the probable speakers. After 1 year of the data being collected, we would delete the records from our system.
