To do that I figure I'd have to have the ability to turn off access to Hub view under Moderator / Map Creator controls for non-graph community members AND a switch that allows me to allow access to Hub View to only those invited to contribute to the graph.

So I need two controls, one of which is already in place.

Private / Public ....

Restrict access to Hub view only to Invitees ...

This way I could invite a group of economists, for example, to debate a particular topic with their efforts being displayed publicly with their identities revealed only as desired and yet with an easy embed (Details view) on any website.
