We’ve added the ability for members to add events to your calendar! You have full control over how much or how little access to give, and which members can add or edit events. Organizations can use this feature to create an integrated or separate community calendar for posting member events.
Also you can setup an event category navigation on your calendar to make it easier for visitors to find events by category.
See our help section on “Allowing Members To Post Or Access Events” for more details.
