To rp more than 2 lines because unless you've got a plot no one is going to get anywhere with 2 lines.
You're allowed to be at different places at one time (make it feesable though...)
Don't leave anybody out or post a comment ("Zara is the greatest") if you see someone else hasn't got a partner (even if you really want to)
No immortality rate, but don't die and come back either (Don't say 'i'm immortal' or die and come back the next day...)
No moves that don't suit your character.
Take it seriously! If I see someone crash a eally deep part of the conversation.... AAARRRRHHHHGGG!
Hate the character not the roleplayer. If you don't like a character, don't hate the person playing them! That's mean!
