I have noticed that most of the questions in Cross Validated come from new users who, for a number of reasons, do not read the FAQ section and do not know about the upvoting and accepting-an-answer system. Sometimes the OP is satistified with an answer but does not accept it because does not know about this. I believe that commenting "you can upvote/accept my answer if you like it" is a bit embarrasing for the answerer/responder as it can be seen as a pressure for doing so.
Given that these rewards motivate people to write good answers (or even writing an answer in this context), I was thinking that an automatic message/comment (such as "consider upvoting/accepting useful answers" with a link to FAQ) on new user's questions might be useful and would not put more charge on moderator's bag of responsibilities.
What do you think about this? Please, feel free to suggest a better option.
