Two communites in North America. One school in flatbush. I’m not at liberty to publicize the names in this forum.
each place runs it their own style.
the basic system is
girls 20-24 date number 1-100 date nubmer 4-400
girls 25+ date number 1-250 date number 4-500.
the school (actually the grade) that is doing it is doing it for girls who are now 24.
They set it up as date number 1-150 date number 4-400.
