Dears, Do you know that if you have an Adsense account you can earn money with out paying 1 cent for site hosting or file hosting I will show you how to do that there is a site http://www.kinguploader.com offers hosting your files up to 1 GB per file with unlimited disk space and unlimited downloads and also host your adsense advertise to appear only when others download your files I tried it and it's great to earn money with less effort Thanks
By the way site also accepts any advertising agency but the advertisement size should be 120x600 or 160x600 pixel
