Sign up to be an interviewer, or to be interviewed as one of your characters.
Note: This is not a performance campfire, but a chance to brainstorm together. If being in character and using voices helps you brainstorm, feel free to do that. If you would rather talk through how your character would respond, that’s great too!  
Likewise, you don't need to be a great interviewer to try it out! We are here to help each other and learn together.
