Hi, David!
I'm sure you will be glad to hear that Hogwarts RPG has now a Spanish translation thanks to the Creative Commons license under which the original was published. Thanks for creating such a great and fun game! Muchas gracias! Muito obrigado!
Here we have our translation, at last on this site:
