thats why it is not easy to find the proper communities, in my opinion, this can be done 'in manual mode' only -- and still no guarantee what you will find is a living places, not just the places staked out. the reason to rely on 'spread the word', ad posts, discord info etc more, then just plain search in 'communities list'.
