For fanworks (only fanfic at the moment but in case that changes):
Transformative Works Policy
Yeah, my basic policy is this: You want to play with my story? Really? Squee! Do you need me to encourage you? I can totally encourage you!
Rough translation: Yes.
This includes but is not limited to: podfic, remixes, sequels, crafts, arts, and commentaries, but excludes translations.
In case you want to change the plot, insert/remove characters, modify pairings, or spin all or a part of mine into a larger story, as an example of how comfortable I am with massive changes to the story: The Man is my remix of Critical Review.
I’d love it if you drop me a link to the completed work, so I can squee over it, but you don’t have to. I’d prefer it if you link back to my story, but if your comfort level doesn’t go there, you don’t have to. However, credit where credit is due. Make sure it's clear the original wasn't yours.
If you need to change my story to make it easier to podfic, yes but the podfic must indicate you’ve changed my story.
For original work: ask me.
Feedback is love. ;-)
