I see Spanish is quite a popular language with many volunteers already; but here is one more just in case. I am a native Spanish speaker from Spain and, as a reference, I was in charge of making the X-Plane 11 Spanish user's manual translation for Aerosoft.
Congratulations for the next step in the network. I was invited a couple of weeks ago, but I have been busy with university exams which I just finished yesterday, so I will have more time from now to test the network and, if needed, help with the translation.
Bests,
