If you see a good fic posted elsewhere, you could always leave the author a note suggesting that they post it here and/or at the Fanfic Archive...
I've done that a couple of times, and that's, for instance, how tvnerdgirl came to these boards - and got nominated in a couple of categories in last year's Kerths
So it's definitely worth pimping the main L&C fanfic venues.
