@SteveBell - You’ve gotten many excellent suggestions here on how to implement a mulit-language project like this. As an example of another multi-language project done in Hype, here’s one we developed in 2015 that’s still being used by the client. You can follow the announcement and discussions here: Large-scale eLearning Site Built in Hype. The live multi-language version is here: http://mysmartmoneydecisions.com/index.html.
Let us know how your project turns out!
