"When selecting your questions and setting your answers, please keep the following guidelines in mind:
- Use question/answer pairs that would be difficult for others to discover or guess. For example, if you often tell stories of your first pet, it isn't a good question to use here.
- Longer answers are better than shorter ones. For example, "Bilbo Baggins" or even "Bilbo Baggins of Bag's End" rather than "Bilbo" for your favorite fictional character."
