Dear mods / admins,
As I've noticed that people often arrive at the English community by Internet search even if they can't write in English, I suggest that you make templates to instruct them in their language on how to change the language setting - this process has been counterintuitive since the forum update.
I think this should be made at least for the most frequent cases like Spanish, German and Russian.
The way I've tried to instruct a member here is a passable example, though you might want to make it even clearer (with screenshots and bells and whistles).
Thanks!
