Great. The simplest way to explain what the contest is about is probably by example. here is a chapter from part one on what I ran an earlier contest.

Look at the comments, then I hope the below makes sense.

Basically, I ask contestants to read the chapters and find problems or potential points of improvement and make each point a separate comment (up to a maximum number per contestant). I will then upvote all non-duplicate comments. My upvotes will act as lottery tickets when I call in croupierbot to draw a winner for each chapter.

There will also be an overall draw, for what every chapter commented on by a contestant equates a lottery ticket.

Have a look at the comments on the chapter I linked to above, and look at croupierbot in particular.
