We too are pleased when our letters page expands and dialogue/polemics develop between readers and authors, and we also agree that queries in letters deserve a response. We strongly encourage readers to send us letters, so that an expanded letters page can become a regular feature of the ISR. As for adding a Q&A section on our Web site, these kind of things won’t be possible until we overhaul and update it, which will happen some time in the next year.
