Every person is to place effort in influencing the Jews in his surroundings, including the children, to perform the Mitzvos of Purim  One is to prepare a Megillah reader, someone to read the portion of Amaleik; Mishloach Manos; coins for Matanos Laevyonim, for the Mivtzaim on Purim. Upon distributing the Mishloach Manos one is to tell the receiver to switch it with another person in order to fulfill the Mitzvah of Mishloach Manos. It is proper to also distribute a small summary of the necessary laws of Purim. One is to bring a charity box to those areas that paupers are not found and then later distribute it to paupers in ones area. One is to encourage the people on Purim to study Torah and educate their children to learn Torah. Just like the Mishloach Manos is to be only be given from woman to woman similarly the spiritual encouragement should only be give from woman to woman.
If one is only able to do a Mivtzaim Megillah reading either at night or by day, which one is he to prefer?
Some write one is to prefer the day reading over the night reading. Others write that one is to prefer the night reading. See Chapter 7 Halacha 4 for further details on this topic! Practically one is to bring the matter to the attention of a Moreh Horaah.
