User blog:CrazySponge/I wish there was a rating between B and C

So, i'm trying to make a rating for my show, SpongeBoobblalaBoBbadanaBloda Pants, Which I think should be 10+, I see I can only choose from 7+ (not the rating) and 13+ (not the rating) I just decided to go with 7+, cause I felt like it was closer.
