There’s a specialized Russian website with it’s forums and a very active community in Russian Facebook-like social network VK.com. I didn’t check the site specifically, but I read the community and there were a few questions about editor localization. Usually those, who already creating something have a basic knowledge of English, but there may be quite a few of those, who don’t get far because of the language barrier. If you don’t mind, I’ll make a thread in Russian with your question translated, in Europe section of the forums and post a link in VK community, as I feel that the language barrier may also prevent from getting the right feedback.
EDIT: Here’s the thread.
