I do think this is a great idea! We were thinking of doing something similar but we decided against it because we thought it might tie our hands quality-wise. We enjoy the ability to choose between different plot lines.
I think we should do it anyway though because we do want different people to participate. I’ll talk to Josh when I see him today and see what he thinks. Thanks! Where do you think they should sign up? (Would it be easiest to put the rule in the guidelines and say “Sign up for the next chapter in the comments section? Or would it be better through email?)
