Here's an example. The BBS website has two editions: English and Dzongkha. Toward the top of each page there are two links that allow you to switch editions.
Say a visitor speaks only English, but happens to land on a Dzongkha news page. Where does she click to escape into the English site? Everything's in Dzongkha, even the link to the English edition. That's not a good idea.
Here is the website as it looks today:
|Uh? What do I click now?|
Here is a more usable version. Notice the difference?
The same issue also exists in the English version. There's a link to the Dzongkha edition, but it's in English.
