How to rate Fanfics:
Here's a small guide which will help you rate your fanfic appropriately.
a) G- This is lowest rating and contains no nudity and little violence. Language is basic and there is complete absence of profanity. These kind of fanfics are generally for everyone and the harshest language you will encounter is "damn", "darn" etc.
b) PG- This rating is a notch higher that G. It contains no nudity and some violence. Language is slighty more mature and profanity is present though in moderation. This rating also includes blood but very little
c) PG 13- This is the most common rating because it inlcudes everything in moderation. There is a substansial amount of violence and profanity. Nudity is present but descriptively and not obvious, eg: She purpuslosey wore a tight and revealing outfit so that she could show off her equipment. There is blood in good quantity with some gore
d) PG 18- This is the rating for mature fanfics. Contains proper and often obvious nudity with usage of words like "bosom". Language is matured with common insults i.e. "son of a..." etc. and the "F" word. There is plenty of suggestive content and suttle sexual sequences. Heavy violence and plenty of gore
e) R- The highest rating, a fanfic can get in the forums. Before you post such a fanfic, it must go through an admin or a webmaster to make sure that it is not too innapropriate. This rating includes, highly descriptive sexual scenes, plenty often extreme and descriptive nudity. Extreme violence with heavy blood and gore. You also require a rather mature mindset to write this kind of a fic.
