recover account

Hello everyone

A long time ago I created an account via github login, changed the username and now I can't access that account. I would like to continue with the same number of solved problems but with my new username.

What kind of information do they need to carry out the procedure?

previous username: JMontanoS.

Please help me Rodion Gorkovenko, this site makes me very nostalgic since it was the place where I learned to program.

pdt: Thanks google translator.

Greetings
