The rating systems.
Ratings: You will see these ratings in the titles of stories to find out what they are rated. But you should also know about sub-ratings. Sub ratings will tell you which universe the story is from. The SEHSAC universe is the largest and most used universe, but occasionally you will come across these other two.
 * 1) G - Gay
 * 2) PG - Pretty gay
 * 3) M - Messed up
 * 4) R - Really strange
 * 5) X - Xvideos Straight up porn
 * 1) S - Super Extreme High School Anime Children. (since most stories are written in this universe, if a story doesn't have a sub rating, it means it's S rated.
 * 2) N - The Neet Nort-iverse
 * 3) T - The Tomorrow Show
