• You can send a message without an email address, but then we cannot reply. We still read every message.
• We use your email address only to reply to your message. We never publish it, use it for anything else, or share it with others (see our Privacy Policy).
• We reply only when a reply is needed, usually within a few days. We may not be able to answer every message.
• If you are a child, please ask a parent or guardian before writing your email address.
