After much thought, I've had the Traditional Chinese wiki at w:c:zh-classical.wolfenstein closed. Interlanguage links to that site have been disabled.
There was literally zero content, and zero edits by anyone other than me. Furthermore, the existing Chinese wiki at w:c:zh.wolfenstein also covers Traditional Chinese material: it actively converts text between eight variants of the language, Traditional Chinese included, via links under the Edit button. So ZH-classical is unneeded.
Editors of the Chinese wiki are still needed. I promise: Make ten good edits and I will make you an administrator of that site! The same offer applies to the German wiki and the Korean wiki. Admin rights are also available for Dutch and Spanish. Polish editors are welcome but you will have to discuss administrator rights with the existing admins.
