League data comes in only through FargoRate LMS our league management software that is tied directly to the FargoRate database.
There are a series of requirements for tournaments, and data is not actually "submitted;" we're merely alerted to public events. Generally, the event needs to be open to a broad swath of people or an invitational with rational criteria (i.e., can't be a hand-picked group of participants playing a round robin). So advertised in advance publicly, cost to participate, use full names for everybody, scores for all matches, and results shared publicly with the world by sharing a bracket on a poolroom website or a local facebook group frequented by pool players.
If you run tournaments, you can give you name and the location, etc to Bryan at

It is also possible to have an individual match submitted through the Salotto mobile APP. You pay something for that; scheduled in advance; both players agree in advance it will go in; both players approve afterward; it remains public on both player's record under "public matches
