The Bowlr system now has 3 main options for creating a new league.
Create new league
The first option is the normal "from scratch" option that has always existed in Bowlr, whereby the league has to be configured using the options available, then generated. This is covered in more detail here.
Copy previous league
The second option is new for 2019, and simply allows the teams or matches from an existing league from any season to be copied to any other season. This is covered in more detail here.
The third option is new for 2019, and is an advanced option that gives greater control to clubs for creating their own fixture patterns and not rely on the system's built-in league generation. In theory, any play pattern that obeys basic round-robin rules can be created in a spreadsheet then imported. This is covered in more detail here.
