I don't think that is something moderator can create, it's up to admin to give us few new boards. IIRC I've PMed him one or maybe more times to create us new board.
Did you get an answer or any kind of feedback on those requests?
In fact, this discussion about the new moderator for the Croatian part of the forum, started a long time ago, 6 years ago, at the request of theymos, as you can see here:
Maybe it's time to have another poll on our board, just to be ready in case we actually get some kind of official reply here. By the way, do you remember when exactly we lost moderator, how many years ago?
I don't remember very well now, it's been a long time but it seems like about 7 years.
What seems more important to me than that is the fact that we had a moderator when there were fewer members and activities on our local part of the forum.
Another important fact is that theymos promised us a moderator and asked us to choose a candidate from among ourselves and propose to him.
We have done this several times in the last few years but we have never received a response from theymos.
So, we’re not really asking theymos to decide whether our local part of the forum needs a moderator or not because theymos have already decided on that.
We only ask him to select one candidate for moderator from several already proposed candidates here.
And if the main condition is knowledge of English, all candidates fully meet it
