quite a long survey but I solved it...
though on the language part you had an option
Srpsko-Hrvatsko (Serbo-Croatian)
I don't know what language you're talking about because that made-up language doesn't exist since the fall of communism in the 90s, I have picked OTHER as my language because I speak Croatian

Thanks very much! And oh man, I know all about the sensitivities around Croation/Serbian/Serbo-Croat...but I couldn't justify listing all three of them as options without also including the Chinese dialects and various other Asian languages with tens of millions of speakers.
