Jon I think what KSUviolet is talking about is eliminating bigs and littles from within the chapter. Offically our campus didn't allow sorority woman to have "big bros" for years and when ti was done it was always stated to be unoffical for that reason. I think KSUviolet is talking about eliminating sorority woman having big sis's competely and same for the guys not have big brothers.
Anyway to the point I haven't heard anything about it, but I am finding I am out of the loop these days.
