yepp i think TaeKim is a Korean if i'm not wrong.

btw, if i use [V]ては(いけない/だめ/ならない), does it sound stronger compared to using conditionals to express "you must do X"? e.g.
(1) 夜、遅くまで電話してはならない
(2) 夜、遅くまで電話しないとならない
(3) 夜、遅くまで電話しなければならない
can we say that (1) is more authoratitive than (2) and (3)? Also, if the meaning of と does not apply here, what will be the difference in naunce between (2) and (3).


Also can たら conditional be used in this way: 夜、遅くまで電話したらならない


As for 「ば」 conditional and 「たら」 conditional, is it true that 「ば」 focuses more on the left part of the sentence, whereas 「たら」 emphasises more on the right part of the sentence?
