ok so i'm trying to make a back up acoount just in case something happens to the one i'm using right now Do I make another correo electrónico to support the other account?

You'll have to make another email.
We aren't supposed to have multiple accounts on fanpop (like anybody follows THAT rule...), so tu can only make one account on your email. You'll have to make a fake one.

tu have to make another email.

duhhhhhhh

Either make another correo electrónico o just type in a fake one.
