Oh if it's _those_ ads, they are generated by Google & Co and relate to behavioural advertising, other sites that may have been visited and cookies, the usual sort of thing. Different visitors will see different ads. and I have already removed the main (Google adsense) banner ad from the home page. You can choose not to accept cookies via the cookie control bar I added along the top of each web page.More details of the web site cookie policy can be found here.
