I came to realize after my purchase that I needed the Publisher extension to make a PMF file. I am also subscribed to ArcGIS Online and was told I could publish my maps there.
1. Can this be done natively out of the box with ArcMap?
2. Can I just follow the steps listed here (http://doc.arcgis.com/en/arcgis-online/share-maps/publish-features.htm) and get my maps available on ArcGIS Online?
3. Will they be publically available doing it this way? (That is what I want)
