I don't think that an FAQ section is necessary because most of the people on this site do not mind answering questions from beginners, even if it is the same question over and over. I think that having people who will take the time to type out an answer to a question that is posted is much friendlier than just clicking on an FAQ link. However, an FAQ section could be useful. It would allow new members who might be embarrassed to ask questions they deem as "stupid" (and I do not think there are any stupid questions) to get an answer without looking like they don't know a lot of info. Just my 2 cents.
