Just a heads-up: for your contact information to appear in your profile, you need to include it in the "about" text area. The "email" field is only visible to moderators.
I think you used the email field which is not actually visible to non-moderators.
Please take a look at my profile and reach out if you are interested in a conversation.
I will only reply to messages if it seems a conversation is warranted. I've had the experience on HN and other groups of someone contacting you with something that looks interesting only to identify you and then go away. Not interested in that at all. I hope you understand.
