Many, many questions have not been answered. I couldn't possibly list them all, but they are easy to find if you use advanced search and search only for unanswered questions. Sometimes questions aren't answered because the question is really hard to answer and requires expertise that few people have. Sometimes questions aren't answered because the question itself doesn't seem to make sense. In either case, feel free to jump in and help us out. Your expertise is needed, whether it is how to fix a car, or how to make a question grammatically correct.
Usually, questions will be answered within 1-5 days. If your question has not been answered by then, it might be because the users here at WikiAnswers are unable to comprehend what you are asking or it may be that your question requires a more complex answer than most are willing to post (if this is the case, it may take more time for it to be answered, so be patient). It is suggested that if your question has not been answered within the aforementioned timeframe, that you try rewording it differently so that it will be easier to understand, or try a different question.
