Thank you very much.
I don't do it any more.
In the end, their spoken language is very broken.
Basically English Slashdotters have two categories. One is those who write their English very colloquial way, and the other is those who intend to use English in academic, more authoritative, formal way. My English classified as very formal, orthodox one.
I don't use expressions that I am not sure, in other words, I only use English as long as I can say it's correct.
As to discussions in Japanese. To hear them speak Japanese, outsiders would take thier conversation for a quarrelling. --Ancient Greek Philosophers -18c Enlightenment Thinkers -Slashdotters
