Form action based on link used to visit it

Hi!

I 've created a form that can populate itself based on the first field (let' say email) that you fill-in, validating against another's form data.
So, if you visit this form and fill-in your email, my application searches on another form's data and if it finds this particular email, it automatically fills-in most of the remaining fields.

However, since I can send personalized e-mails, I want to urge specific people to fill in my form through a personal link. Something like:
http://creator.zoho.com/myaccount/myform/form-perma/myformname/xxxxxxxxxxxxxxx?EmailAddress=mymail@myplace.com

Note that I've put the specific e-mail address in the link.
What, I need is this: My form should understand the "?EmailAddress=mymail@myplace.com" part of the link, and use the email address in order to populate the form (if it finds a match that is).

Is this possible?
