Lon, since you started this story, I think, by default (or as punishment,) you get to be the one to assign chapters to writers. I believe P.G. Barnett is writing chapter 4.

Terrye Turpin has volunteered.
And so has John K Adams.

Perhaps you could put a schedule of chapters and who is writing them on the first chapter, to make it clear who is writing which chapter. You can just assign new chapters as writers volunteer.

Thanks.
