• Please don't flame (direct a vitriolic or abusive message at someone), everyone is entitled to their opinion and attacking people because you disagree with them over a piece of fiction is rude and inappropriate. We all have things we're excited about that others don't like.
• Remember Hanlon's Razor: Never assume malice when something could easily be explained by ignorance or neglect. If someone says something that seems odd, or isn't clear, always ask for clarification first! Make sure you're on the same tennis court before you start volleying shots (and even then, be nice and play fair).
• Keep NSFW content in the appropriate discussions; Not everyone wants to see it and not everyone can view it safely. Same goes for topics likely to activate traumas or gross people out.
• Be excellent to each other! Being rude to your fellow chummers over the colour of their skin, the way they represent, their biological enhancements, or who they fall in love with won't win you many friends or allies. 
• No spamming please!
