Hi all, I'm new to Excel, having used MS Works for a customer list/database
for many years. I'm trying to decide whether it would be best to have:

1. A single Excel workbook with my entire customer list on one worksheet
or
2. Seperate workbooks for each month
or
3. A single workbook with worksheets for each month.

My goal is to easily be able to select customers from a certain month and
export their contact information to direct mailers, etc, for promotional and
reminder mailings, etc.

Thanks for the advice..
