QueryString, Forms, And Variables

I have a page with a link. The link says "Contact Me" and the code behind it is:

<a href="testcontact.asp?Recipient=dhalro">Contact Me</a>

Then when you are sent to the testcontact.asp page I have:

<% vName = Request.QueryString("Recipient") + "@hotmail.com" %>

<form method=post action="/email/forms/contact.asp">
<input type=hidden name="Recipient" value = "<% =vName %>">
<input type=hidden name="Subject" value="Test">

Followed by the rest of the form.

I know my contact.asp page is funtional because if I put my actual e-mail address in as the value it works.

Now I'm wondering if this is correct or even close. The reason I am doing this is because I have multiple pages with different usernames and I want it so you click a link and it passes the username to a form (i always want to use the same contact form) and then the person can just fill out the form and it send it to the appropriate person.
