One slightly different option for this week: Start a new thread with the name of a character or place. Include some description of when that character or place was introduced. Continue adding to each other's posts and expanding as characters and places continue to develop as a way of keeping track of characters, names, places, things that have happened. It's a big sprawling novel and I think that this could be a useful way of keeping track of important details (include page numbers for reference sake).
a) Name of a character
b) Description of when the character was introduced
c) Name of a place
d) Description of when the place was introduced
