A few years ago, Alex Ott started up a Russian version of Planet Emacsen over on defun.ru. They’ve been having some hosting reliability issues, and so I’ve agreed to host it together with Planet Emacsen on the same machine.
You can now find the Russian Planet Emacsen at: http://planet.emacsen.org/ru/
You can find Alex’s announcement (in Russian) on his blog.
If any other language communities would like their own Planet Emacsen [I’m looking at you, Japan! :)], just ask!
