HEY, YOUNG DINGDINGERS! Stay safe: Never tell anyone your email address. We take your feedback just as seriously as the feedback we get from grown-ups (in fact, a bit more seriously between you and me) but we don't need you to tell us your email address. If you'd like a reply, please ask a parent or teacher if you can use their email instead.

If you're a grown-up and would like a reply, please ensure you enter a valid email address. The Dingding team read each suggestion carefully, and will respond presonally by email if appropriate. Of course, we're very careful indeed to respect your privacy.
