A little late to the party, but here be the stuff I'm currently writing.
You may, without asking:
Translate any of my works
Remix any of my works
Transform any of my works (including podfics)
Share/redistribute any of my works

I only ask that you:
Provide a link to the original source
Don’t make any money off it
You do NOT have permission to upload my works to any database, including Goodreads.
Also, you can find information on citing fanworks (such as Decoding the Subtext--archived elsewhere) here:
