> Email: In my profile
The "email" field in your profile isn't public. You need to put it in the "about" field if you want it to be public. That's why users have been replying to you in the thread here.
This has been a common misunderstanding in the past so we actually added some clarifying text to the profile page a few weeks ago! https://news.ycombinator.com/item?id=28016257
