I had been thinking about asking this question with an eye toward making it a yearly anthology on CafePress. (In reading the Lulu explanation above, I see that they are likely the same thing with different names.) My question was to involve the possibilities of no profit (except obviously CafePress or whomever would make some, but no extra above that cost), profits to go to the forum somehow, profits to go to some charity of choice, and so on.
Cost there would depend on how many pages, but it wouldn't be prohibitive.
My thinking was that each month's total collection of stories would be its own chapter, and I figured that the first year's book would just be a bit short since it started in April -- rather than going from April to March for each year's collection. (Yes, optimism is rampant here--but the challenge shows no signs of slowing down.)
So put me down for a yes, whatever you're doing. (Ahh, the advantages of procrastinating in asking this question come clear -- now someone else is doing the work, and not me!
But I would also be happy to help if you need any assistance in paginating and formatting it all for publication.)
I would not be averse to fixing punctuation and spelling errors, but otherwise the stories should remain as they were entered. Slippery slope, and all that.
