If you have enabled suggesting events in the Group Settings, group members will be able to create events themselves by using the option Suggest Event.
When the event is created, you will receive an email notification to let you know an event has been suggested by one of the group members and asking you to approve it
You can follow the link in the email to review the suggested event, or you can find it in the Organizer Dashboard >> Events >> Suggested.
You can now choose to Approve, Edit, or Delete it by using the options on the Actions dropdown.
It’s a good idea to review the event before you approve it. You can do this by clicking the Event title from the Organizer Dashboard, or selecting Edit from the Actions menu. You will be able to work with the event like with any event you have created yourself, using event tools.
Make any edits to the event details then, when you are happy with it, you can approve it.
Once the event is approved, it will become visible to event members the same way as events posted by organizers. By default it will be hosted by the group member who suggested the event.
You can announce the event yourself or leave this to the Host.
