I'd like to put some opinion on this thread.@riddler
I disagree with the notion of a multilingual site due to who says your not going to use your native language to discriminate others back talk to others who are not native in that language. All the while English is a world wide language that everyone understands yes at various levels but still enough knowledge to get by.
I also agree it would not hurt to have the ability to publically speak a native language but even as you said you Sorta know Spanish. With the inability or confidently say you fluently speak Spanish, bolds a question whats the purpose of this thread if you yourself Sorta speaks Spanish.
Furthermore some moderators I'm not sure only speak English-language.
Yes it's very hard when this type of topic comes up when there are numerous probabilities but try and think of the many ways other sites and people have created web sites.
I myself know 4 languages yes not all fluently as I hope for but enough to go by. They are French, Spanish, German, and English.
I have no trouble with these 4 languages yet I'd perfer to speak english due to its the only language in the world that nearly everyone know and I must repeat at various levels.
Yes I understand your concern and or wanting something done due to native languages but somethings are actually more helpful then what it looks like.
