Sounds nice! A word of advice, instead of claiming 120 languages, I feel it would be better to focus on a few an ensure that they work well with native speakers.
Additionally, please try it out before assuming they’re just claims. I’ve been using it daily for 3 months in 18 languages (roughly one from each major language family), and been in pretty constant contact with native speakers.
True I cannot vouche for all 120 languages, and sure there is the occasional error in the lower resource languages. However, I have put in a lot of work to make sure I have a representivie sample, and the errors are currently well within an acceptable range — and I’m working hard to improve them!
Figured you'd appreciate the complexity of having that many languages on a site. jw.org.
