In the year 2008, I had created my email torocarlos@hotmail.com, with my last name and name, but this was blocked for a long time and I had to create other accounts with the initials of my full names, that is Carlos Enrique Toro Borrego and the year 2008, remaining (cetb2008). From there all the accounts that I created I put the user cetb2008, since it became a custom for me.

Would you change the username?

I would not change the username, since my account has the initials of my names and surnames with what I identify in all social networks and I feel comfortable with this name.
Then I show you my picture on a mountain, since I like to go hiking in the open air, to enjoy nature.
