You can have a schedule be public but hide the surfaces (tables or boards).

This happens when a league doesn't want to assign a specific table at a bar. They would prefer to use a first come first serve basis.

To hide the surface they play on go to Round-Robins. (Menu > Manage > Brackets/Round-Robins > Round-Robins)

1. Select the league 

*Tip: Or multiple edit all leagues at the same time.

2. Pencil to edit

3. Public Visibility and Display Options.

4. Uncheck Surfaces.

5. Save.
