That is correct, we do not have an "official" instance or an "official" magazine. What follows now is MY OWN opinion, other community members might think differently.
Mbin is aiming for a federated and decentralized social network, I think the whole point of the fediverse is that there shouldn't be one main instance, right? Feel free to create a magazine where ever you want! Isn't that the beauty of activitypub? Maybe the idea takes some getting used to.
Your community members ("I do love Mbin") are expressing that they are unhappy with the mediums available for discussion and feel excluded. What is done about it?
I feel a bit of negativity from you. This will be my last reply in this thread. She has resolved it herself by creating a magazine by herself on Mbin for Mbin: https://kbin.run/m/Mdev
