Why the browser user agent string?

If I have firefox and IE installed on one machine, could I vote twice, once 
from each browser?

Let me see if I understand the concept - 

Email is sent with a link to an html page. The link could be of the form:

http://some.web.server/form.jsp?vote=no

The page then captures the vote = no, and displays a thank you page.

How can I get the email recipient's email address in the query string? For 
example:

http://some.web.server/form.jsp?vote=no&email=member@yahoo.com

Mailman doesn't have a mail merge function that I know of, so I can't embed it 
when I send the email.

Thanks!
