<Snipped quote by ArenaSnow>
The common ground would be "Given an infinite amount of space, everything that can reasonably exist will exist, and it'll be duplicated even further out, with some of the duplicates progressing at different rates of time." Beyond this, each thread would functionally be its own spacetime. They don't need to focus on specific locations, and could even be centered around certain objects, people, or other things. Whether a thread is Open or Closed is up to its creator, but each thread in the subforum would be part of the whole that is the Expanding Horizons. Nobody would be forced to roleplay with anyone else, and everyone can split off into their respective threads if they can't find a common ground. That way, everybody collectively decides which stories they want to participate in, with all contexts being agreed upon as they're presented.

I don't really see the point of this over just finding a gig in the casual or advanced forums.

If you're just going to close a thread while going in an infinite space-time where there's no real common ground besides infinite mumbo jumbo, then what would even be the point of being in a special PW in the first place? You could always just assume that other roleplaying forums, in their own way, are all part of a vast, creatively unlimited roleplaying universe.
