Q. If a group of friends makes a Seudas Purim Koton is it considered a Seudas Mitzva that one invited should attend?
A. Horav Shlomo Miller's Shlit'a opinion is that if the participants say Divrei Torah and sing songs of prize to Hashem for the miracles of survival received as it should be, it becomes a Seudas Mitzva.
