I think it would be much more beneficial for you to ask for a local moderator. You have several very active members who, if they are ready to accept responsibility, should perhaps apply for local mod positions.
Merit source applications to reward quality posts more are okay, but spam removal is perhaps more important for maintaining the forum. In the end, it will be easier for you to discuss if your board is spam-free.
I beg to disagree. While global mods can still delete spam (having their onw local mod would be of course better), not having separate child boards is imho more important and should be priority. Imagine if on our local board we don't have child boards and instead everything is crammed in one and if it was 10x as active.
Regarding them getting their own local moderator, it mainly depends on the amount of spam they have there so unless its a real problem, chances of them getting one are not good.
While I am glad to see that you started request topic, choice of child boards seem kinda strange to me. Wouldn't it make more sense to put off topic and politics&society into one child board, while asking for some other boards like "altcoins" (once bull market start you can expect increase of intresest in those, or maybe even marketplace if there's enough interest.
Anyway, I hope that you get new child boards as soon as possible since you are one of the most active local boards and you are in a real need for at least a few.
