I'm currently rewriting my MS and want to send it to several friends/family that I know will not pull punches when critiquing (No high school students ) before submitting to an agent. Questions: Is this common practice? Do I need to worry about copywriting material at this point? When do you begin to worry about copywriting material? What should be the punishment for somebody who eats the chocolate and vanilla and only leaves you the strawberry in your Neapolitan ice cream?
