What are you talking about? There is a fanfic section. There are clubs devoted just to fanfic and if you want to add a fanfic story to any spot you use the article section and choose the fanfiction option.

I think Kitkat means a fanfic section in each club, like there are currently sections for images, videos, polls etc.

It'd be a good idea. I know that currently you can add fanfiction as an article, but it'd be better if it had its own separate place. Atm it can be a bit annoying if you're looking through the articles and not actually searching for fanfic. Alternatively, you could post links to fanfics written elsewhere.

What you're describing sounds to me like a club within a club. I don't see the point to that. Like I said, there are clubs devoted entirely to various kinds of fanfiction. Also, if people use their keywords properly than you could search within a spot for the kind of content you're looking for- including fanfiction.
