The event host will send a link out via email to all registered participants if the event is online. If the event is in-person, you should receive an email with the location information. If you have not received your confirmation email, please reach out to the host whose contact info can be found under the event description on your Calendar page.
Remember, events will vary based on the format the host chose when creating the event. They may have the option for online registration or in-person registration for the same event. Make sure you decide before registering which event access better suits you. Once you've decided, only register for the single event/ attendance you would like.
