Call for speakers in now open through 25 May.
A completely open-ended enquiry form offers no suggestions as to topics or what the conference tracks will be. But the website claims 8 "streams", 50 sessions, 110+ speakers.
Here are speakers already signed up.
Organizers are also seeking exhibitors (another open-ended form).
