When editing your event you can choose from three options regarding the visibility of your event:

• Everyone (public event): The event is public, can be seen by anyone, including users outside of XING and can be found by search engines.
• XING members only: The event is only visible to members who are logged in to XING and can be found by members using the events search.
• Only people on the guest list: The event can only be seen by people you invited and, in some cases, by participants who’ve already said they’re going. If your event is a group event also group members can see it. When selecting this option your event won’t be found by members using the events search anymore.
