One more question for you, Graham Hudgins:
When sharing the hub site with someone outside your Organization, how do you configure the link for them to get there AND log in to their account?
In Firefox: I am attempting to open the Hub page as a user from another Org. When I do, the Hub site does not open, but it does forward me to ArcGIS.com without asking for me to login. If I use the "Sign In" link provided there, I am just taken to the Org's home page after sign-in.
EDIT: I just tried this in Chrome, and it works as I would expect - taking the user directly to a page asking for credentials. It appears that this does not work with Firefox....
I would like the Hub site to open and ask for a log in, and go directly to the Hub site after authentication. Is this possible in Firefox?
Thanks,
--Adam
