I’m pretty sure there is no official stance on this. It’d be entirely up to your discretion what you want to do there. I’ve read some pretty adult stuff that’s been published through Inkshares, as well as some on the complete opposite end of the spectrum. I don’t think anyone’s going to force you to change the voice of your storytelling here.

Try WeVideo (.com). I’d never made a video in my LIFE and was able to figure that one out. (It’s also what Christopher Lee used to make my FAOII trailer which you can view here: https://www.youtube.com/watch?v=dt5c9g70uCo)
