I'm glad to announce that, after a few technical problems, the Spanish translation of this topic can be found
here.
Thank you. It's added to the Op.
What were the technical problems faced?
The problem was that Gazeta wasn't able to see it, due to a certain glitch in the forum.
Please be aware that nothing can be seen there...

I made a little change in the text following the suggestion of a member of my local board and most users have no problem to visualise it, but Gazeta is still having problems with it. I think that he will eventually open a thread in Meta to find out what was the cause, and a solution.
