There was a sincerely large lapse in our language rule that I've corrected. It was known through word of mouth to some, but I've put it down in text. It pretty much adds up to 'Keep the discussion appropriate. No cursing, drugs, sex, politics or religion.' Religion and politics are included more to avoid unnecessary heated arguments, as those topics generally devolve in that direction. Because this wasn't stated explicitly, I understand some adjustment will take time, but we expect that adjustment to begin within a reasonable time frame.
