@dang doesn't work - you have to email hn@ycombinator.com. That's in the guidelines: https://news.ycombinator.com/newsguidelines.html. Fortunately another user alerted me that way - it's the only reliable way to get information to us.

A nice side effect is that it doesn't add off-topic meta stuff to the thread.

p.s. I hope that didn't sound too critical. I appreciate your helpful intention!
