It takes nothing except simply being a fanfic.
I am working through all of the fanfictions in the Fan Corner from past to present and it can take a long time. I have part of an update done (collected links and need to format them), but I've recently changed computers and I haven't been able to touch it.
If you want yours in right away, simply post the links to them and their titles. Otherwise, I'll get to them when I get to them, but if they're recent it may be a while.
