Address Merge using Smart Tags?

[Lloyd]

I would like to be able to select a persons name from a
list from within Word 2003 and have their name and
address entered into the letter that I'm writing,
including having their name appear in the header of all
subsequent pages. Historically we have used some code to
pull these names from an XL spreadsheet. However, it
seems clunky. In Office 2003 isn't there any easier way
to do this using either Smart Tags or XML?

Thanks in advance. Lloyd
