@jon @miaq Anyway, here's the plan:
1. Set up some kind of multihoming Mastodon service.
2. When the themecamp listing comes out, make one instance for each theme camp, like <campname>.camp.social. Hopefully this is cheap!
3. Invite the listed contact to their instance (do the listings still have a contact email?).
4. They can invite their campmates, moderate the instance, etc.
5. <fediverse intensifies>
