CSS is a far cleaner way to remove it than actually editing the code... You don't want to have to worry about people editing the wrong thing, even if you clearly define the area
I put this in my "Header Insert" on the html inserts page
<style type="text/css">
.footer form { display: none; }
</style>Or you could drop this into the "Extra CSS" in your style:
.footer form { display: none; }
