Please accept apologies from an am haaretz who assumed people would understand that I meant siman shin in mishna berura. I forgot there were talmidei chachamim like yourself who would turn to the original shaarei teshuva.
Thank you, but the fault for that is mine. I should have realized which Shaarei Teshuva you meant and had I not been so uneducated, it probably would have occurred to me before I penned my “poison letter” post.
