Hello!
I'm sorry for the confusion. I'm not actually with coopcycle.org, I'm one of the admins on lemmy.ca . I made this post to ask if it would be ok to invite them and see if someone here would like to take this on. I'm in Canada and French is not my first language, so it didn't seem like my place to talk to them :) I'm happy to do it, but I figured I should at least speak to your team first since I would be referring them to one of your instances.
I agree with you that Piefed makes more sense for their use case. I was thinking that they could set up a community here instead of their Facebook page, which doesn't seem to get that much engagement anyway.
Language wise, I am more fluent in English. I'm sorry for the poor French, I didn't get a lot of practice after learning French in high school.
