Unable to log-in

[Shin4an]

Hello and sorry in advance for the bs inquiry.
It's just that I can't remember the e-mail I've registered, so there is no way for me to finish the 2-way authentication. Would it be possible for a mod/admin to type as a reply the first and last 2 letters of the mail, including the domain it is on (Google, Yahoo, ABV or other)?
Thank you.

P.S. I don't know how I can post with my current account which I am not supposed to be able to log into. I guess I am not entirely restricted but it would still be better to know my e-mail.
