Thanks for your kind words @jayna!
We haven't got any suggestions yet for Chapter Three, it's been a little slow on this chapter. But hey! All I need is a single suggestion to write it! The more the better, of course! And I may follow your advise and do another post promoting it.
But to tell you the truth, even if it ends up having only a handful of people engaged in it, or not making significant rewards, I don't really mind. What I like is that we tell the story together and you keep me motivated to write!
Yes, I would definitely put the Chapter 3 challenge out as a new post. You'll get some good suggestions then, I wager!
