If you check out the memories of polyfandomrecs, I used to rec a lot of SPN gen fic. So if you're looking, it can be found...

But yeah, I agree that Charmed fic can be harder, mostly because the only place that seems to have a fandom these days is on FF.net (SCARY is right)...

And dude, I have to admit. I did like both the Fast & Furious movies...Paul Walker was so hitting on Tyrese in the second one and I *loved* it.
