Oooh, can you do that? Nah, I wouldn't. One thing it looks like a good chance to do is offer my services in fandoms where I've seen the source material, I know the characters, but I don't feel confident enough to generate whole story ideas myself (a lot of TV/movie fandoms fall into this category for me, since I always feel more secure with text-based stories: I could try PotC, Torchwood, Battlestar Galactica, Star Wars...)
