What is Signposting in debate?

Signposting tells your judge where you are: "On their first contention... My second response... Now to our case." If a judge can’t place an argument on the flow, it may as well not have been made. Good signposting sounds mechanical in practice and goes unnoticed in rounds, because the judge always knows where you are. Pair it with numbered responses and your rebuttals become very hard to misflow.
