As this project appears to be fairly unknown in the fediverse still, I’d like to use this opportunity to advertise Flohmarkt. This Fediverse equivalent of Facebook Marketplace already has some instances up and running - see here: https://codeberg.org/flohmarkt/flohmarkt/wiki/flohmarkt-instances

The developers are always open for discussion on their IRC channel: https://web.libera.chat/?nick=GithubGuest%3F#flohmarkt

Please feel free to host a local instance for your city/town and invite friends and family to post. Flohmarkt relies on local relationships and pick-up items only rather than shipping stuff worldwide.
