Users posting public events will now be able to turn on roll call, a new feature which allows users to rsvp to any user-submitted event. This feature makes it possible to keep track of who is attending a particular event be it a convention or a group dive. Attending users show up in a list for others to publicly see. It is highly recommended that any open event take use of this feature although the poster of the event retains the ability to enable or disable this option per event.
