Virtual circles are like virtual round tables or rooms. Event organizers create circles to help connect event participants in live video chat to discuss certain topics, or just network and meet each other.
We have two types of Virtual Circles:
Public Circles: first come, first serve. It's open for all event attendees and the organizers set the limit of participants per circle.
Private Circles: used for private meetings or pre-scheduled meetings set up by the event admins where they choose certain attendees to participate in the circle.
Circles have a limit of 20 participants ( using video and audio ) and another 150 listeners who can listen to the conversations but can't participate.
Circles are only created by event organizers (admins only) and can be scheduled before the event or created on spot during the event.
