Hi there,
Congrats on launching the audio fics! I noticed it said that if someone didn't want their stories read and recorded they should let you know, but it doesn't say how. I just wanted to suggest adding it to the profile page. You can click whether or not you are a beta reader, so perhaps another item can be added as to whether or not you would approve your stories as audiofics. Either that, or when the mods make a decision for the next recording, you could contact the author. But then, you might not hear from them all, and if you can just check their profile page, you are good to go!
Good luck with the new feature!
