Can you elaborate - what is kna shull
IINM, that's Rich Roberts' shul.
Not sure what he's referring to, but my first thought goes to the sign about how to solicit money from him. He has precise instructions to send a handwritten letter, and how to lay it out. He has a comment about "If you are not willing to spend time writing me a letter, why should I spend time reading it," or something to that effect.
ETA: I feel bad mentioning his name without saying how big of a tzaddik he is. I took my family to his chol hamoed carnival this year, and I am overwhelmed by his generosity. He spends so much to allow other children to have a really enjoyable time. Was perhaps the best Chol Hamoed trip this year, and it didn't cost me a penny.
