Just found this!

If you have a favourite TV show (and can’t get enough of what’s on the screen) check out Fan Fiction, for stories involving your favourite characters written by other fans.

Their TV Shows section is here.

Personall I intend to check out the following sections:
The A-Team.
The Bill (Those that know me well – know I’m an avid fan!).
Spooks

And there’s loads more I want to check out after!
