Hi @pablomp, I don't really know steemit, and am not aware of a direct messaging functionality here, but you can contact me either via a twitter message (my name on twitter is the same as here) - I can then message you my e-mail address in private, I'd just rather not post it publicly like this.
Also, sorry for the late response, I was not aware of your comment here.
