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
I love that you called it the lingua franca.
Why yes, English is the French.
Uh do you not know what “lingua franca” means or are you making a joke?
