you know guys, if you wanna know what theme a website is using, Just Right Click on its logo and see the image location, its gonna go something like this - ***://***.websitename.com/publicHTML/WPcontent/Themes/THEMENAME/Logo.gif lol this is what i always do But in some cases like this one, people change their theme folder name to the site name eg :decentweblog.com/wp-content/themes/decentweblog/images/decentweblog.gif So in that case you cant know the theme
