Woody:
The version uploaded is based on the original code contributed by Dave Kennelly at open-operations.com since that is the code both myself and Pinghead started with over a year ago.
The reason it is not based on the PingHead version of the code is because that version did not exist a year ago when we began making additions and improvements to the original contribution. We have, over the last year or so improved and added new features independently of the version of the code Pinghead had been working with.
I did difference the two versions recently when I was told of that version's existance and although they are very different (our version is form based, uses POST to specify a selectable date range rather than just using a fixed GET date, improved database schema, etc.) I could detect very few distinguishable feature improvements between the two because as it turns out we both probably made many of the same bug fixes and feature improvements during that time period.
As I've said previously though, if there is something I missed in the previous version that is important and doesn't exist in this version I'll try to add it, just let me know?
