cypher.space and Amethyst have marketplaces that are interoperable with us! plebeian.market is also becoming interoperable, but are also another (soon to be) working option to shop with.

I saw a notification about your note on just getting started on nostr:nprofile1qqs2xugc5jyguqkj36rk0syv4tmnkjdtmtperttl7x9rqjy3ustdcvcppemhxue69uhkummn9ekx7mp0qy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7qg6waehxw309aek2mnyd96zumn0wdnxcctjv5hxxmmd9uxa0uz8 but I can't find the event, so I DMd you and am replying here instead.

If you go to the top menu and click on 'my listings' you should be able to add a listing from there!
