Why does Marvel have an "A" rating on some of their more "all ages" books? If you go to their website where they explain their ratings, they do not explain what "A" means. So..
A. What does it mean?
B. Why do they use it, if they don't explain what it means?
C. If it means (as some have speculated) "Adolescents," why not just use "All Ages," which they already have as a rating?
