I’ve got to say, a lot of your responses seem like you are pre-convinced that there isn’t any solution to your problem. I think that’s why you’ve been getting so much snark/pushback.

Did you read Schmorp’s full story, or just the one link I sent? I know it’s not step by step instructions, but if you’re serious about organizing something I feel like there are a lot of good tips you could pick up on from the way that they did/are doing things.

Do you have any libraries you could frequent? Many of the unknowns you have could be addressed at a library and I think they would have much more relevant answers pertaining to your locality.

Also, here’s a link to something that I just saw here, that seemed like it could be potentially relevant/useful: https://mobilizon.fr/
