PBA: Why? How many members do the BDA and RCA have? I assume that’s either pretty close to or over the 100 already. And if there aren’t enough I’m sure they’d go straight to all of the YU Roshei Yeshivah and Kollel Elyon members. That’s at least another 60 or 70, I think. If the BDA ever needed to get an HMR they’d be able to do it without much cost or trouble.
Also, I asked someone at ORA, for whatever that’s worth. I was told that in their history they’ve had several hundred women contact them whose husbands were refusing to give Gittin or go to Beis Din. They’ve had less than 10 men asked to be represented.
