Translating translatewiki.net itself
Fragment of a discussion from Support/LiquidThreads
I've translated the site messages to Frisian recently. There was a reference to it under Special:LanguageStats, but it seems to be gone now (except Twn Main Page). The translation tool isn't accessible via the system messages either, so searching the MediaWiki namespace seems to be the only way.
Cheers!
