Great suggestions as always, Jay. Thank you. I think the group option comes closest to a solution, but all my in-world readers still want to visit and engage in the out-of-world elements at some point.
As for the second instance, I feel like it would segment the community, and I’m already spending a lot of time managing one.
Basically I’d like a plugin where I could choose a custom permalink and then hand select the categories that show at that link.
