"so why doesn't someone"

Bill, these words are the problem of your question. Alison was the only "someone" who saw this project through to the end. It will probably be a while before she will be of a mindset to tackle such a project again.

Now, if you should want to be a "someone", please go ahead with the next calendar.

I'm not really picking on you here and mean no offense. There are many of us who might have done more. But I know how little help Alison actually ended up receiving with the project after the "someone"s fell by the wayside.
