By keeping it secret no-one has to worry about having the first chapter, which apparently is a thing.
Yes please awesome
HELL YES COUNT ME IN.
I’d love to play again! I had so much fun the last time. 
This sounds great, I’m in.
And I want to point out that in my official role as Evil Overlord, I’m highly qualified for this Apocalypse edition.
This sounds like too much fun to pass up! I’m in!
Thank you! 
I’ll take the first one if no one wants it. Then everyone else will have to guess who is a dolphin shapshifter, who is a raging rumaholic and who has a secret life as a time traveling pirate!
I’m in!
Bless you, you crazy man.
Please count me in!
Thanks for doing this, Rog. Count me in!
Oh, I’d definitely write much better if I knew my chapter were first. Or if I had the skill.
I think the uncertainty of it all - genre, plot, chapter - is part of the appeal. I much prefer not knowing and having to guess. I’ve been consistently wrong about the placement of my chapter every time.
I’m in, if you’ll have me!
Oh, this is exciting. New account here, sign me up!
I will participate.
Woot! I am absolutely in. (But I had some trouble with remembering my last password and it wouldn’t send me a new one so I had to re-register–my last username was jdeckstrom)
I’m in.
Oh, yes please! 
I’m in - Thanks Rog!
Sounds fun! I’m in!
Love me some apocalyptic espresso.
