Other than Pakistan, there are other communities too which are active on their local threads like "Укpaїнcькa (Ukrainian)" and "বাংলা (Bengali)" and they are also waiting for their local board.
Yes, I think all those local threads that you mentioned should be considered when during creation of new local boards. I also agree that there are some boards with very less activity but as they have been on forum for sometime so I believe they should also remain on the forum.
Ultimately, it's Theymos's decision because only he knows better that when new boards should be created. I hope Pakistan and all those mentioned communities may get their local boards in 2024 as a gift when Bitcoin crosses its ATH.
Well, I am not saying that the local boards that are not active should be converted back to local threads but all I am saying is that there are only 3 or 4 local threads that are active and if those are converted into local boards, it will be good for those communities who are waiting for their local board for quite some time now.
Also, i believe that it won't be a much administrative task as the local threads have already mods assigned, and they can continue to be the mods when those threads are converted in the boards.
