1.) Thou shalt not be lost. Or else.
Using characters from the original anime is okay, but if I see any characters who just happen to be 'Natsu's long-lost sister', I will personally come over through the computer and STRANGLE YOU.
2.) Thou shalt not kill.
Don't kill other people's characters without permission. It's just dumb, annoying and kind of mean. Similarly, don't say 'Sir Bob the mighty used his superbeam and beat everyone.' Fights aren't fun if nobody else can participate.
3.) Thou shalt not... be creepy.
Mild romance is okay, but please, people, can we keep it PG, or at the very least,
PG-13? Before you post something, think about this- what would a poor, wide-eyed bunny do if they read it? Mild violence is okay, but please, can we not describe how mangled every organ was? You're scaring the bunnies.
4.) Thou art not Mary Poppins.
We don't want any Mary Sue or Gary Stu characters. You know, the ones who are practically perfect in every way. Because the fact is, nobody is practically perfect in every way except Mary Poppins, and before you ask, no, you may not be her.
5.) Thou art not the god of this joint.
No powerplaying (again, Sir Bob cannot take out everyone at once) or god modding (controlling other people's characters). It's not fun. If it's something like, "Bob hit Joe, which made Joe go OWIE!" and Joe isn't your character, that's okay, as long as it's not something like "Bob hit Joe which killed him" or "Bob hit Joe so Joe ran to a different part of town and went to be the king of the rats, and then he came back with a ratty tooth and bit Bob." That would be tremendously boring.
6.) Thou shalt not ruin a bunny's life.
Mild is the key word. Censor excessive swearing. Romance should be mild. We don't need to be able to see every cut on Mark's lungs to understand that it hurts. If a bunny wouldn't wanna read it, neither do we.
7.) Thou shalt not be a jerk head.
We're all friends here. Respect everyone else. That's just common sense.
8.) Thou shalt have fun without ruining someone else's.
This is made for you to enjoy yourself, but not at the expense of others.
