People within your community who sign up to join your ArcGIS Hub become members within your ArcGIS Hub Community, a separate but linked ArcGIS Online organization, that comes with a premium level ArcGIS Hub license. As members of this organization, people from the public can create an account, manage their user profile, sign up to attend events, store data downloads, follow initiatives, respond to surveys, receive relevant notifications and emails, and create story maps and web maps using shared data.
