However, I happen to be a Youtopia volunteer, currently working on my own Spanish translation of HPMoR:

Neat! You should get Eliezer to include it in the list.

(By the way, I should say that having multiple translations of the same text is very valuable data for language-learners such as myself -- so let me make an appeal to would-be translators out there not to be discouraged by the existence of another translation in your language, whether complete or not.)

I was aware of the translation you cite, but I can't remember having noticed that the translator was Colombian too.

(I concluded that he was because he had a Colombian Creative Commons license for his blog. EDIT: Also, I just noticed that he gives his specific location: Roldanillo, Valle del Cauca, Colombia.)
