Matched, www.matched.co.uk

Basically, if you have a web site(s), you can go to matched, enter the details of your webpages into their database and they assign adverts to your site. They match your sites with suitable advertisers and pay you £3 per advert per month. You can enter up to 5 websites, with up to 5 pages in each one, which could make you £75 extra a month, for doing virtually nothing! I did it, and every month, I get £15 going into my PayPal account. Well worth a look if you ask me!
