This is a follow up to this post .
When the Bostoner Rebbe (of Boston and Har Nof) was asked by approached by a female congregant who expressed the desire to say Kaddish, his response was 'Beis Yaakov lechu ve-nelcha'. When this woman would say Kaddish, he made a point of standing next to the mechitza so that it would be clear that he was responding to her Kaddish.
Thanks, ADDeRabbetzin, for the story.
You won't find this story in the ArtScroll biography. You won't find this either.
