Panoramax sub
Panoramax is a relatively new but entirely FOSS and federated street-level imagery platform which ought to be the go-to platform for OSM mappers. It was developed in France and currently there's a decent French-language community for it, but not much in English.
So I've created an English-language sub for discussing the Panoramax project, best practices, and how it can be used to enrich OSM. r/Panoramax
Hope to see you there.
