I am glad you like Whonix and appreciate your efforts! A Chinese language snippet in the title is okay.
According to wiki translations, I personally cannot work on this. It’s up to @Ego to see if/how we can proceed. I guess Ego will reply to this thread in near future.
Overall, whatever works best for your community. I am afraid non-English language support is not better than it is, but as I understand, everyone including you already know we are struggling with our overall mission (low funding, low man power, etc.)
We have an Arabic sub forum but forum administration wise we were not able to support it that quickly and great yet. Has some issues. ( forcing Arabic language by default on the Arabic section - #2 by TNT_BOM_BOM )
If we fail to well integrate non-English languages at whonix.org, then likely other community pages will pop up. That is natural and fine.
If it seems helpful to you, and if you’re willing to moderate it (on topic Whonix, no spam, no violation of laws, what not), also a Chinese sub forum could be created. If that even works. (With Arabic right to left not so great.)
