Use custom subscriber key with Exact Target Web Collect

I’m using ExactTarget’s web collect functionality to collect new sign ups from our website. I want to use a custom subscriber key when a new subscriber account is created in ET using web collect but it seems like web collect uses the customer email address as the subscriber key. Is there a way I can pass subscriber key in the query sting. I have tried it but it doesn’t seem to work.

See code here. harded coded “[email protected]” for testing purposes.

   <form action="" name="subscribeForm" method="post">
<input type="hidden" id="thx" name="thx" value="">
<input type="hidden" name="err" value="YOUR ERROR PAGE HERE" />
<input type="hidden" name="usub" value="YOUR SUCCESS UNSUB PAGE HERE" />
<input type="hidden" name="MID" value="1069927" />
<INPUT TYPE="HIDDEN" name="Subscriber Key" VALUE="<a href="" class="__cf_email__" data-cfemail="eed7d7dec3df9a8b9d9aae9a8b9d9ac08d8183">[email protected]</a>" />
<INPUT TYPE="HIDDEN" name="Email Address" VALUE="<a href="" class="__cf_email__" data-cfemail="45772d242d2c2105312c262e203128243631203731316b262a6b302e">[email protected]</a>" />
<INPUT TYPE="HIDDEN" name="lid" VALUE="32347" />
<table cellpadding="0" cellspacing="0" border="0">

        <td><input type="radio" name="Email Type" value="HTML" checked="checked" />
        <font face="Verdana" size="2">HTML</font>
            <input type="radio" name="Email Type" value="TEXT" />
            <font face="Verdana" size="2"> Text</font>
            <input type="radio" name="SubAction" value="add" checked="checked" />
            <font face="Verdana" size="2">Subscribe</font>
            <input type="radio" name="SubAction" value="unsub" />
            <font face="Verdana" size="2">Unsubscribe</font>
            <input type="submit" value="Submit" /></td>
            <td align="right">
            <font face="verdana" size="1" color="#4C5487">
