how to contact a guy on codechef?

I would like to contact @vijay_cipher to ask a question about his solution on Rohith and Circles problem
from last july challenge. Is here anybody who knows how one can do it over codechef?

anyways, it’d be nice if codechef had such opportunity.

A Google search gives his HackerEarth profile and I am sure HackerEarth has a user messaging feature. You can try that if it’s really urgent.

Thanks a lot!!

although name seems to be different one from the codechefs one. Are you sure this is the same person?

His name is “Vijay kumar attri” on both accounts. Also the branch (CSE) and college are same. I think that is enough to believe that they are of same person.
