Can I run events with tickets, confirmations and reminders in Votel?

Votel does not sell tickets for entry to something like a city fair.

For event content and community activity, use Communities. For booking a class or an appointment, use a bookable in Calendars and set reminders under Notifications (email, SMS, coming up soon reminders and so on). For an email blast that asks people to fill out a form to confirm, followed by reminders closer to the date, build a follow-up sequence in workflows.
