Minor thing, don’t call it “Western style” or “Eastern style”. I’m not sure what the correct term is.

There are plenty of Asian countries that don’t follow last name - first name so it’s not necessarily an “eastern” thing.

another opinion from me about automating based on country. It’s a cool thing to implement but might not be worth the effort.

An example I have is in the Philippines, majority of people go First Name Last Name. However, there’s a Chinese sub population that has last name first name. But then most of this sub population also have “Christian” names that they use in Most official documents or websites. I’m pretty sure other countries will also have similar nuances.

Maybe a screen name or username will be the razor.
