1) If registering for a canon character, check that this character has not already been taken.
2) Each member is allowed to register two characters maximum.
3) If you are playing a canon character, make sure you stick to how they are represented in the books (eg: Klaus probably wouldn't say that books are useless, and Esme wouldn't start hating fashion. You see what I mean.).
4) If you have any more questions, please PM me.
