Van this is the third time you have asked this question but you won't listen. We cannot give you an accurate answer if you do not tell us which site you are using. I have already given you three options, but you need to be able to install these on your site. Your site may already have purpose built scripts specifically designed for it, which makes your life so much easier. Unless you want me to write a whole script for you which you wouldn't know how to implicate, just tell us the name of the script you are using. Or give us a link to the web site. Just click the edit button.
