As a forum for professional feedback, submissions of letters are open to all. You do not need to be a subscriber. To avoid redundancy, we urge you to read other people's letters before submitting your own. Name, current appointment, place of work, and email address are required to send a letter, and will be published with your review. We also require that you declare any competing financial interests. Unprofessional submissions will not be considered or responded to.
