I'm an expert in the field with a book published in Spanish: "NO SE PUEDE TAPAR EL SOL CON UN DEDO" undertitled: "La divertidísima historia de los antiaparicionistas guadalupanos metidos de historiadores y su fracaso final" Mexico City, 1999. And two websites, one in Spanish: www.ennombredeguadalupe.blogspot.com ; and English: www.veritasliberabit.blogspot.com.
I have made additions and corrections under my URL and as Luisosio which have been totally and unjustifiably erased.
I hope Wikipedia may help in keeping some order to see no more vandalism occurs.
