- I like the abridgment of "Worldbuilding" to "WB"; it's less typing and a smaller potential for error while nominating.

- If you want "No Characters" to indicate "the characters involved in the worldbuilding is secondary to the worldbuilding itself", then "No or Any Characters" is indeed clearer.

- I agree that the distinction between "Fanfiction" and "Meta" was minimally helpful at best; the idea of the Meta category could easily be incorporated as prompts for the other categories. I have no opinion on the inclusion of podcasts or vids.
