How to use the site
How do I modify the spreadsheets on this site to meet my needs?
All the Excel workbooks are write protected to make it harder to corrupt them accidentally, but they are not secured with passwords. You are therefore free to modify them in any way that you wish. We do not have the resources to support further development of the workbooks and so any enhancements you make to them are "at your own risk". Please observe the conditions of the project's CC licence.
