Not just classifieds... Nip-99 is also getting an overhaul... forget stalls... the new term will be "collections" but you will be able to use collections to create Shops, or Categories, or sub categories, or services etc

The new NIP-99 will be a blend of NIP-15 and NIP-99 but a lot more efficient, versatile, and a far better understanding of decentralised ecommerce on nostr 👍
