There are a large number of questions being asked by first time users who have no idea how the site works. Many have used Google to find out "Why won't my Ford truck start?" and they get directed to Ask. They think that they are on a Ford service site with an interactive program. You will see subsequent questions about "Why haven't you answered my question?". I have even seen a school teacher demanding to know where the books are for her students (what book, what class, what school????). If a question is the first or second asked by someone, do not expect an acknowledgement. I think most people who have been on the site for a while and have been active will comment on an answer or give a thumbs up. You can only try.
