I started a website a few days ago,
The Source, for all kinds of fic- both fan and original.
It's started off sort of slow, but I'm hoping for it to pick up. It's not just to post fics and review them, although that was the primary intent, it's also intended to be a place for people who write, who want to write, or who have simply thought about writing, to be in contact with each other. A place to discuss what we've done, what we'd like to do, and the challenges we've run across.
Please check it out? Maybe even sign up and post some of what you've written? (If you write for a fandom that isn't represented, just let me know and I'll be more than willing to set up a forum for you.)
Caution: The site takes all fandoms and all ratings. I've tried to set it up so nobody should be surprised to find a story with a lot of swearing, violence or whatever- the stories should all be under appropriate ratings, which are clearly labeled and explained.
