I have a list of 75 users that I would like to send a standard email
to with their user name and password along with general information on
how to use the program that I emailing about.

I was hoping that I could set up some sort of Mail Merge. I can set
up the document OK; but what I am trying to figure out is that I just
want to send an email to a specific person with their specific logon
and password.

I originally used Word to set up the document and put in the data
fields (stored in Excel); but when I merge, it creates one big
document that it sends to all people in the contact list.

Is there a way that I can send a form letter/email with specific
information to a specific email address.

Without knowing what version of Word, it sounds like you're merging to letters
rather than to e-mail. Take a look at Word's help for merging to email.
