Word to the wise. If you are an ArcGIS Online Administrator - there is a little known setting in your Organization settings for your users that must be set to "Enable ESRI content". To do this, click on "my Organization", then see your users, click on the gear symbol next to a user that you want to have access to GeoNet or "ESRI Access". Click "Enable ESRI Access". This allows GeoNet to work for them.
