I give blanket permission for my fic (such as it is) to be used in transformative fanworks (i.e. podfic, exotic dance, art, mashed potato sculpture, etc.) in the unlikely event that someone wishes to use them in this way. I merely request a link to the finished product. (For squeeing purposes you understand.)
A note on repods: Well, really that's really between you and the author, but for what it's worth, If I start a fic/series, I'll finish it, never fear.
