I was resently upgraded to Microsoft Office Professional 2003, and one day
while playing around with the different menu's I noticed the document
properties option. I decided to take a look. Well after a bit of exploring
I knoticed the custom tab had several custom fields that I did not create.

Example
Author
email addresss

My question is this did I do something to create these (I don't believe I
did) or is this something that Word 2003 does automatically?
