Barchu

From Halachipedia
  1. One may sit while the tzaliach tzibbur says Baruchu and then only stand when answering the Barchu. [1]
  2. According to Ashkenazim, the accepted minhag is to bow during Barchu. [2] According to Sephardim, many have the minhag to bow slightly while answering Barchu and have what to rely on, however it's preferable not to bow. [3]
  3. If one continued Seudat Shelishit into the night (past Shkiah) should still say Retzay in benching, even if one answered Barchu. However, if one already said Maariv, one shouldn’t say Retzsay in benching. [4]
