yes, it is a meta question for a nft board topic with a few sub topics... could all be sub tpoical to altcoins but seems like the wrong place since alts and nfts are apples and pineapples.
There cannot be a separate board for every niche tooic, especially if it's about altcoins, cause the forum is majorly Bitcoin oriented. The altcoin discussion board is the most appropriate section for posts related to NFTs as they are considered altcoins and your post would not be acted on by mods, except it is low value or for some other reason, if topics in relation to NFT becomes very popular there, then a push for a child board can be made.
