on the email error message there's a typo:

Por favor, introduce una direccione de email valida. Por ejemplo, "fred@domain.com

It should be:

Por favor, introduce una direccion de email valida. Por ejemplo, "fred@domain.com

Also I've noticed that there's no acute characters where they should be:

direccion

should be:

direcci&oacute ;n (there's a space there because this editor parses the acute code)

There are a lot of other ones
