First: Always use " for IC (In Character) RPing ex: "Hey, how are you?".
Second: Always use () for OOC (Out Of Character) talking ex: (That's stupid). And make sure to end it with (IC).
Third: There are 2 types of RPing (I know of) 1 being: 1st person ex: *Punches in the face*. And 3rd person ex: He'd/She'd punch him/her in the face.
