1. Literacy is important. Good grammar, coherent sentences, etc. It's very important to a story. I am not asking you for perfection; we all make mistakes. A minor slip is no big deal. And please, post 1-2 paragraphs at minimum.
2. No god-modding. No controlling other people's characters. Make it a fun experience for everyone!
3. Treat each other with respect. RpR is a family, and we treat each other as such. Just minus the constant bickering between siblings.
