Shy-la: If nobody bangs on the table on Rosh Chodesh before Shmoneh Esrei, do you still have to say Yaaleh Va-yavo?
What about on Purim? And if you miss Yaaleh Vi-yavo on Purim, do you have to repeat the Shmoneh Esrei?
Is there a difference between Maariv and the other tfillos like on Rosh Chodesh?
