None of the unclaimed states have anything set in stone for them, so you're mostly free to make up whatever you want for them. You can also alter the borders however you want as long as it makes sense. There is no one in particular that you need to talk to about any of the Russian states, but there are some players in Russia, like myself, that you can ask specifics to since we're the most in tune with what's going on in that part of the map. And nah, you don't have to PM anyone. I meant that if you wanted to ask specifics, you could PM me, but you don't have to.
