N.C.I.S. Fanfiction - is there any on this site and if so how do I add to it?

I've written a couple of short fanfiction stories based around N.C.I.S. and I would like to share them with N.C.I.S. fans but I don't think there's a fanfiction page on this site. Please forgive my stupidity if there is, firstly I'm a techno-numbskull and second I'm still learning about this site.

Thank-you kindly for any help.
