It would be great, yes. Our concern has been that the price of the book depends on the # of pages, and we don't know how many there will be in advance. More importantly, we don't know if enough people will write, to make a physical book worthwhile. What we're planning to do is give that option to the person who starts the book, and let them specify that the book should be printed only if it has 5/10/15/20 letters...

Thanks much for the suggestion.
