Jumping in here to say that, in that case, I will go change the adult-content settings! I hadn't realized that it would actually block people out rather than giving them a warning.

Right now there's absolutely no adult content there. It's possible that there will be later, when the fic/art goes up, because that depends on what people create, but we'll make sure anything explicit is clearly labeled as such. And everything will be LJ-cut anyway.
