Our club spent 3 meetings yelling over spoilers, then we tried a 20 page cutoff and it just stopped
Back in January we had two people quit over a plot twist in the Pickett book because a member spoiled a death on page 300 while we were on page 120. We started posting a hard page cutoff in the chat before each meetup and now nobody argues, we just talk about the part we all read. Does your group use a page limit or do you just wing it?
