Words You Should and Shouldn't Use
I'm not talking rules-wise, but you should be aware of what you're allowing your character to say and what you say either way, but more role-play-wise.
I do not recommend using wolf-speak! I repeat, I do NOT recommend using ill-experienced role-player, or anyone for that matter, to use wolf-speak!
On the topic of wolf-speak (using words like "tiara" for "head", "pillars" for "legs", etc.), you might get confused and really lost. Just because some role-players say "Literates Only!" doesn't actually mean that they are advanced role-players. They especially aren't if they use wolf-speak, no matter how they use punctuation, spelling, spacing, etc.
If English isn't your first language, I really hope you try to stay away from people like this, or you might be confused. If you speak English, I hope you never use language like this.
If you really need help coming up with cool words for a specific part, then you're either not using the word correctly, or you've used it too many times. Perhaps you need a new way to describe your character.
Lucky for you guys, there's already a thread on this topic:

No-Nos and Do-Dos
I have to agree with most: Gary/Mary Sues are almost everywhere and are some of the power-players, god-mods, insta-killers, etc. So I can understand why this rule is put there.
However, the most that I have agreed with prior to this sentence would already know that this rule wouldn't be needed for "literate" role-plays, since no advanced role-player would actually ever Gary/Mary Sue.
For example, this is what a pesky bugger--Imean, Gary/Mary Sue can do:
"tom wanted someone to mate with. he felt alone but didnt cry in his corner. i love you. he muttered in his sleep. his beauty glowing in the moonlight attracting all females and making them jealous of him and wanting him. its always happening. he thought."
Now, now little children reading this, this isn't the best way to get a mate, (you shouldn't mate at all, but you can have your characters in love, of course~!) since nobody can be that beautiful, nor can somebody make all the female wolves/whateveryouare fall in love with you. In fact, this is a big no-no!
Back on track: I think this rule isn't really needed at all, since most already know not to do this. Some might do this, but I still think you don't need to tell someone like "You cannot do this", or "You cannot do that", or something like that, (that might just be me...) and tell them before warning them if this rule isn't added.
I really hope you don't have a bleak idea from that quote on role-playing, it's more than just dos and don'ts.
All you really need to know is that people don't like Gary/Mary Sues (perfect characters), god-mods (perfect characters that can do anything they want), power-players (characters who don't use realism), insta-killing (death no matter what), or anything like that. c;
