Just a small tip. If you want to view a pdf and you don’t have adobe acrobat (or any other pdf reader) installed, e.g., you are sitting in a cyber cage or at a friend’s place, you can still view it. Only thing you have to do is, just prefix the url to the online pdf with “http://www.scribd.com/vacuum?url=” and you’ll see a nice web interface rendering your pdf without having to install anything on your PC.
e.g.: url to pdf: http://abc.com/readme.pdf
So final url: “http://www.scribd.com/vacuum?url=http://abc.com/readme.pdf”
