1. Pick a Harry Potter character that is not already taken, or make up a new one.
2. Act like the character you pick. And if you want to be Fred or George, and there isn't another person to play the other twin, you may act as both. And in the place of Draco, for Crab and Goyle, if someone is not them already, the one acting as Draco may act out their parts as well....basically...you can act out any character as long as it is not already taken...but you can only have one character listed as yours with the exception of Fred and George, or Argus Filch and Mrs. Norris one person can have both of those characters.
3. If someone has a problem with someone on the RPG, then do not bring it up in the RPG, message [Boomnesss] about it.
