I want add a missing venue to Untappd or I want to add my home location as a venue. How do I do that?
So your searching for your venue, and you don't find it. Now what?
Untappd uses foursquare for all venues. To add a venue, you need to create a foursquare account, and create a venue using their mobile app. Once the venue has been created and you check-in into it - it will show up in your search in the "Add Location" screen.
I repeat, we cannot create venues in Untappd, all venues must be created in foursquare first.
