Can be done with MS Office. Use MS Word to make the master document. Use MS Word or MS Excel to maintain the database of addresses.
Does she have MS Office? If so, what version (XP, 2003, 2007, maybe even the Mac variant)?
I might be able to post a link to Microsofts help info, once I know.
A friend of mine runs a small business and wants to create a mailing list of customers and then import these names & info on mailing labels. She is not very computer literate beyond surfing the 'Net', watching movies and email and wants to use just one program to perform this. I have a program called MyMail List and am not sure that that is what she is looking for. She used to work for Mcdonald's in administration and said that she would import names onto mailing labels in one step. I think she used the company's Intranet for that purpose. Anyway, any help is appreciated and respected.
