DCinside AW m.gallary is the most biggest South korean AW community in my knowledge. And we have 300s players in discord(very actives are +- 150s), and consider who not use discord n only use web board, it will be some more. so maybe 300~500 i guess. and there is other smaller communitys some like Korean CC operating one but usually both communitys are not communicate each other so i dont know their size.
