Seeing new discussions about this, I want to ask. Has anyone reached out to FontAwesome trying to find out if they can make their documentation available in China ?
I'm surprised I can't find a single discussion about this online. Maybe they just don't know about it.
We're not the only project using fontawesome, and I believe it would be in FontAwesome interest to fix that on their end.
It would make sense for Chinese users to contact them directly, not the Flarum team. You might also be able to help them troubleshoot why it's blocked.
