In the bottom right of your event page, you'll find the link "Claim it now" shown below:
When you click on the link, we will try to confirm that it's your event based on the event platform we sourced it from.
Facebook sourced event
If it's from Facebook, we will ask you to connect your Facebook profile so we can confirm that you're a manager of the page that owns that event.
Eventbrite sourced event
If it's from Eventbrite, we will ask you to register with Evensi, if you didn't do it already, and then contact us to associate the email you used in the registration process with the event page.
After this process finishes you will find the event claimed under Menu > Events created or under Menu > My pages, depending if it was just an event or a page.
