Hm I think a lot of those named ranges aren't used.

What I'm thinking as far as the changes was just to push a new excel spreadsheet out to people and they would click the button to bring in all of their project data (those date tabs). I'm not sure if this is what you mean by changes. I will be continuing to optimize this workbook so eventually when version 4 comes out, I want people to be able to make a really easy transition ( a lot of people don't know or would have a ton of trouble copying sheets and updating the values to get rid of links)
