Can be anything you want us to talk about. Anything (related to the book).
This isn't required and you can always bring things up in the comments when we open the discussion post in a few days, but whatever questions or discussion topics you comment with here will have the option of being totally anonymous if you're totally shy like that. Or want people to for-sure see your question/discussion topic/whatever.
Comments are screened, please tell me whether you want your username attached to your question(s) or not.
