Hey @andrewsawesome!
That truly is awesome!
Reasons why the English forum is so much more lively is of course the outstanding quality and timeliness of your answers!!! But also the fact that English-speaking users still is by far the biggest portion of our active members.
That's a bit of a hen and egg problem, because in order to get more people to use our forums in the other languages, we kind of have to provide more content first and/or assure that their questions get an answer. What we've been doing so far from our side to make sure that good content is also available for forum users in other language subdomains is that every 3 months, we'd look at the top 10 Answers in the English forum, see if they make sense to translate, and then post a summary with disclaimer and backlinks to the original, like this one, for example: https://de.ifixit.com/Antworten/Ansehen/....
I know that's not much, but it's a start, and all we could implement so far with the limited staff we have for the other languages.
Machine translation is of course available if one activates the toggle below the language switcher on the top right, but we only point out to it if necessary, because we don't want to "lose" the few active members we have to the English forum :-) Also, I think that while you'd be able to read a translated version, the answer would probably only pop up in search results when one types in the English words. I'm not sure how exactly you imagine the moderation option: Do you think of having a feature to click on that would then machine translate question and existing answer(s) and comments over to a foreign language forum? If that's what you imagine, the question would be why we'd use a feature instead of always automatically having a post go live in all languages and then asking the global community for help...before we can start looking into potential new functionalities, we'd have to spec out a bit what exactly we want and what would make sense. Please add your thoughts here if you want to take part in that, I'd very much appreciate!
For now, I think the best way you could temporarily help until we see the user base grow in foreign languages, if that's not too much to ask, would be to try answering new questions directly in the subdomain forums for any language you may speak or you may also use deep.com, which does a way better job than google translate from English into other languages.
If, on top of that, you'd be interested in taking part in posting or putting together those summaries for translation, I'd be totally happy to help in any way I can, with a Meta-post of top 10-20 English answers every 3 months for example?
THANK YOU SO MUCH AGAIN for bringing this up, for your interest, and @oldturkey03 for your willingness to make us truly a global community!!!
