Event feed has been released to all event creators on Prekindle.  You can start using it immediately.

What can I do with Event Feed?
Post content to your ticket holders.  It works similar to a Facebook post, but comments are not currently supported.  Examples of posts you may want to create: lineup additions, information about vendors on site, contests, say thank you & more.  Learn more here.

How do I access the new tools?
Look for the megaphone icon   on each of your events on the dashboard.

Do I need to use Event Feed?
Nope.  Use it only when you need to reach out to your ticket holders.
