Oh, yeah, they did. They're response was that they haven't actually come to a decision on meta yet, but will alter their terms of service when they do. They told me that AO3 wasn't policed, so as long as no one reported me, I could do what I wanted. Of course, someone HAS reported me, so now I'll have to what whoever reviews the complaint decides.

So, yeah, I'm unsure whether I should keep posting meta there or not. Decisions decisions.

I actually don't talk about the "history" behind Merlin (and I'm assuming by "history" you mean the original myths, right?). The show is so liberal with the legends and myths, that I just like to treat the show as it's own independent thing.
