Many times Rav Willig commented that he enjoyed the articles and their thoroughness. He also explained that these articles did not represent his personal pesakim on the issues mentioned except where his opinion is specifically mentioned, in which case, it was always confirmed that the article represented his opinion accurately. I also wanted to express my gratitude to a dear friend, Aviyam Levinson, who made a great effort and spent a lot of time editing these articles.
