Bueno mi pregunta en si es, alguien descubrio una manera sencilla de comparar las contraseñas del phpbb3? o conoce este framework... ya que mi ultima opcion y la menos deseable searia generar una contraseña a los usuarios y que la active mediante e-mail xD pero aveces no llegan los mails, pero ese no es el caso...
