And RE: The GL/Nova Corps, that is entirely within the choice of whoever applies for and gets accepted for either a GL or a Nova. Until that time comes, leave it vague.

As for the extent of mutant knowledge, the public knows they exist, but I don't imagine they know the sordid details of stuff like Weapon X or Xavier's School, Genosha or anything like that. Though that, too, largely falls under the umbrella of whoever wants to flesh out The X-Men. 

Also, due to real life commitments, I'm gonna have to postpone the IC's launch until 8PM tonight. So... forget that 12PM business.
