That's perfectly cool! Now that you explain it I see where the selection emphasis was coming from. And since you're doing it specifically to focus on the porn, it's good to know that was a deliberate choice.
Sure, I'm personally disappointed that I can't really participate in this round, since this had been my favorite IJ comm to write for. But in a way it feels better to know that genfic is being selected-against deliberately (i.e. picking these kinks specifically for sex) rather than accidentally (i.e. all kinks were eligible but the only ones chosen happened to be for sex)?
(And the notion that it might not be all-sex-prompts for all future rounds is kind of reassuring to me too... I really would like to write for future rounds, unless the community focus is going to be redefined as 'specifically for sex' from here on out, in which case I'll figure out how to deal when we see the next set of prompts...)
