Transformative works policy: While I have not written fic, I have posted podfic and meta on the Internet. Anything that I've publicly posted is, in my opinion, no longer in my control anyway, and I am comfortable with that. Use it however you would like! All I can do is make a (completely non-mandatory) request that if you transform my work, you treat it with kindness and respect, whatever that means to you.
Also, I do not think that permission from a podficcer should be *at all* a requirement for repodding, but just to put it out there, I am comfortable and happy with the idea of other podficcers making their own podfic of any work I have done. Basically, I don't believe that you need my blessing, but if you want it, you have it! (If I'm in the middle of a podfic WIP and you are working on a podfic of the same fic, I'd love for us to touch base and discuss the possibility of synching up posting schedules! But again, of course, that's just a preference and not something that I expect or that I want anybody to feel restricted by.)
Also, if you are an author and would like to create a transformative works policy, that would be AMAZING. You can find more info on that here.
