When creating a tournament, you can attach a location for the tournament. In most cases, this is a public place with a name and an address, but the address can be omitted for private events.
A new location can be created only when creating a tournament by selecting the Create new location from the Select location… dropdown.
Adding a location helps your players. The location is displayed on Match Play Live so your players can see where the tournament is taking place. It's recommended that you add a location with an address to all of your tournaments.
All Locations page
The All Locations page will show you a list of all locations you have created. On that page, you can also edit existing locations, changing their name or address, or you can retire a location. Retired locations do not show up as an option when you create new tournaments.
