How to contact the author of a post in the sandbox?

Question

Habr

I was looking through the sandbox and suddenly came across a letter addressed to me - habrahabr.ru/sandbox/68524/
Is there a way on Habré to contact the author and answer the letter?

Answer 1

You can give him an invitation and write in profile.

Answer 2

Most likely not. could leave some data for communication in the habraprofile. and they could contact you just by looking at the habraprofile.

Answer 3

In general, it is strange that registration on Habré is open, a person could register and write through personal messages.
