From the organizers:
"It is called the Community Leadership Summit and has keynotes, a full "unconference", and social events. The event brings together people passionate about community to evolve how we build strong communities. It takes place at the Austin Convention Center from the 6th - 7th May 2017 and is also entirely free to attend (although you need to register at http://www.communityleadershipsummit.com/register/).
* 9 keynote sessions covering topics such as building contributor programs, organizing events, running content websites, measuring community, governance, collaboration and workflow, diversity, and more.
* A full unconference where the attendees define the sessions. This results in a fascinating set of discussions across a rich set of topics.
* Social events the evening before (as a pre-meet to meet attendees), and on the Saturday night (to get know people you met at the event more). This will include free drinks and food."
