Transformative Works Policy:
Yes, I encourage remixes of all sorts, including podfic, fanart, and fanmixes. If there is a story that I'd rather not have podficced, I'll make a note on that specific story. Other than that, it's all fair game! :)
I don't want for anyone to feel pressured into informing me of a podficced work, but if you do podfic a story of mine I'd really appreciate a link back to the original AO3 post.
Also, if this information helped you, please consider posting a transformative works policy of your own. That'd be wonderful!
