The royalties check just comes direct from Stark Industries, probably.
I'm not sure, I haven't looked too much into which podcasts and things have made it over to this place. I know sometimes even when things aren't available here they'll show up if people seem to really miss or really want them, so maybe if I wish harder it'll make it through. I'm not sure how it works.
I'd be interested in checking out Uncover too - I love like, learning about things I might have missed.
