Need some help to streamline my very large 2003 excel workbook
 

I have built up a reasonably complex workbook for the purpose of recording
statistics for my local darts competition. It works very well but I feel it
needs an overhaul. It has 11 spreadsheets with some fairly big data bases and
over 60 macro modules, the whole workbook is around 14mb.
I am wondering if someone would be willing to have a look at it.
