In my country (non-english speaking), facebook is definitely the default for group organization and it really bugs me. I don’t want to use facebook, so I end up not organizing with anyone in the surroundings. Then someone set up a Telegram group and that was sort of an improvement, but impractical, and still nobody posts events.
First time I read about Mobilizon, it fits the bill of every local community internet thing facebook is currently having its dirty corporate fingers on. But what kind of server would I need to set it up? Any old laptop run from home good enough?
