How to comment on a sandbox article?

Question

Habr

Hello everyone, sometimes I read this site, I found an article in the sandbox that I have been reading for a long time, but in a different form, I don’t know where to ask a question, I’m trying to find out here. How can I comment on it or something like that?

Answer 1

This site does not have a sandbox.
if we are talking about habré, then you can’t comment in the sandbox.

Answer 2

thanks, I thought so, then it turns out if I do not agree with that text, then I can’t write it anywhere? or more advanced users evaluate sandbox text?
