Big Update: For the Beta we will be adding on a test group of users in the coming days/week. The app is meant to be GEO locked. Meaning you can not see ledges past 20 miles. With today’s build (version 20141114) we have added an “Extend” button on The Ledge screen. This is done so all beta testers can interact with people as it’s currently a small testing group.
You can still create private Ledges and Inclusive ledges that are only seen by local people or people you invite to join in the beta.
To take part in the beta you need to be a member of this Google community first https://plus.google.com/communities/104649030195462412878
After you join that beta group you will have access to use the app.
