Nah, I have thought about that in the past. But then you have deadlines that I would likely miss frequently. There are times I don't get on the message boards sometimes weeks or months at a time when I am busy. I have been pretty good this last year about keeping up.
I still like the open end book idea so I don't have to worry about deadlines. I would just keep adding on as I go. Especially if I get the ranch because I will be really busy then for a while at least.
