Drupal supports multiple languages. I didn’t yet figure out how to
make it automatically show the translation at bitcoin.org/zh-hans
though.
Does Drupal have any special multi-language support, or do you just create copies of pages by hand?
BlueSky offered to do translation on the forum. If you create a
www.bitcoin.org/zh/copy of the site and give him an account with just the ability to create new pages and edit text, he’ll probably translate the site into Chinese for you and maybe maintain it.
