You do not need to ask my permission to remix, podfic, translate and create art for any fanwork I have posted. You should include a link back to my work (preferably to it's post here at Ao3), and I would prefer it if you shared the link to your work with me -- I'd love to see it!
I enjoy collaboration and am fairly open to it, in whatever format: podfic, cowriting, arts, etc. You want to work together on something, contact me - the easiest way is probably via a polite comment on a recent work.
Where works are collaborative, please check the other authors' transformative works policies; my permission is a given.
When it comes to writing sequels to any of my fics, please ask first.
