Let's document interactions between Mobilizon and other fediverse softwares. Documentation is up to date with Mastodon and Gancio (https://docs.mobilizon.org/6.%20Fediverse/1.protocol/) but inputs regarding Peertube and Pixelfed are missing (at least). If you use Mobilizon together with Peertube or Pixelfed or any fediverse other software, we're very interested in your experience. #fediverse

What is Mobilizon? It’s an alternative to Facebook groups and events, as well as Meetup.
Today’s news is that we’re releasing the brand-new version, 5.2.4 (https://
framagit.org/kaihuri/mobilizon/-/releases/5.2.4).
I invite you to check it out and (re)discover Mobilizon.
For example, you can use https://
mobilizon.fr, the Framasoft instance, for activist events, or
https://
keskonfai.fr, the Kaihuri instance, for any events in France.
