The default stages that come with every forum are not a one size fits all governance process. Communities should adjust the stages to fit their unique governance process.
To setup custom governance stages in your forum, visit the “manage community” page in the top left admin dropdown. There you will find a field to edit stages. Follow the format of ["Stage 1", "Stage 2", "Stage 3",…].
Ensure you use straight quotes not curved. (i.e. "Stage 1" not “Stage 1”)
