How do I use this jQuery plugin to delete a cookie?

First, to show the cookie, I used code from electrictoolbox.com. Then I made a form to add some cookie: ``` <form class="cokies" method="post"> <input class="query" name="q" type="text" /> <input type="submit" name="save" value="saving"> <a>Delete Cookies</a> </form> ``` ``` $(document).ready(function(){ $('.cokies a').click(function(){ $.cookie('q', null); }); remember('[name=q]'); ``` This function is from komodomedia.com: ``` function remember( selector ){ $(selector).each(function(){ //if this item has been cookied, restore it var name = $(this).attr('name'); if( $.cookie( name ) ){ $(this).val( $.cookie(name) ); } //assign a change function to the item to cookie it $(this).change(function(){ $.cookie(name, $(this).val(), { path: '/', expires: 365 }); }); }); } ``` The problem is, I can't work out how to delete a cookie.
