How can I make my event public vs. private?

When creating your event, if you keep the “Allow people to RSVP via my event page” option checked, then your service event will be open to the public for anyone to sign up. Event organizers will get an email once someone RSVPs for the event.

If you uncheck the “Allow people to RSVP via my event page” option, your event page will be displayed on the site but other people won't be able to sign up.

You can also hide your event page completely by checking the "Hide my event page" option.
