Q. Does the one getting the aliya (on Parshas Zachor) have to have in mind to be moitze (discharge the obligation of) the people with the bracha of the Torah, and tell them also to have in mind to be yotze?
A. Orchos Chaim (O.H. 140) quotes that the Chasam Sofer would do so (See also Nitey Gavriel 19: 2.)
Horav Shlomo Miller's Shlit'a opinion is that we don't have such tradition and it is unnecessary.
