1. Users can create re:gions which are drawn on a map. If a user joins a region they can receive posts as they pass through these areas and also contribute to the re:gion. Users within a given re:gion's area can post to the group’s page but any user outside of the location can only read posts.
2. Outside of re:gions, when users post to the ‘commons’ their posts are tagged with the user's current location and are made visible to other app users within a certain radius.
