Batch Editing Observations With Private Location

If you go to the Edit Observations page (accessible from your logo at the upper right, or from the Observations tab at the top of your dashboard), you can search for them using Geoprivacy. At that point, you should only see the Private ones. Then you hit the Batch Edit button, Select all of them, and Edit Selected. There should be a block that says Batch Observation. Click on that, then More Fields at the bottom of the block. At that point, you should see a field for Geoprivacy.
