No offence, but considering the ongoing war russia started against Ukraine, I believe it is a little bit cruel to suppose that Ukrainian speaking users would want to write in russian board, communicate with local members and be cool with that.
While I sympathise with their struggle and I can imagine what they are going through as my country went through similar thing ~30 years ago, no one is forcing anyone to be active in Russian local board.
So, if they want their own local board, the least they can do is to actually be active in their local thread and if we learned anything when it comes to creating local boards is that theymos won't create new unless there is a real need for one. ~60 posts written in the last year or so shows that they are not really interested so why should forum staff bother?
