Hi, kei.isomura-san. I have a question. Is there any particular reason that you "comment" instead of "answer" ? If you don't mind, how about to post your answers as answers, not as comments? // When you "Answer", you can start new paragraph with proper spaces in between. It should be much much easier to read. // Also, viewers can see that there is already an answer when browsing the question list. If you "Add a comment", there is only "0 answers" . Thanks.
