User Roles are an important piece of the Resource Center pie. User Roles provide users specific permissions within the Resource Center. Before understanding User Roles, you need to be privy to how Organizations work within the Resource Center.
User Roles at the Viewer, Member and Operator level are determined by the Organization. For example, a Viewer Role in Organization A does not have Viewer Role permissions in Organization B unless this user has been invited into Organization B. However, the Viewer Role does have permissions to view all of the Divisions within Organization A.
