To invite people to your page, your page must be published first.
Once it's been published, you can invite people to join your event by clicking on "Participants" from your page’s left-hand side dashboard. Within "Participants," select the plus sign at the top of the page.
Enter the email address of the individuals you want to invite to participate in you event. Once you select "Send Invite" the individual will receive an email instructing them on how to join your event.
Users can also join from your event page, so if you want to put together an email blast or invite people on social media, you only need to share the link and instruct people to click “Join This Event.”
