As far as I can tell, Slideshare is a scam. I had to sign up for it in order to rent a film. It is somehow connected to Linked In. I have tried to cancel the account but there is no menu item to do so. I got a message that I've have a contract to use the site for three months before I can cancel. I don't remember being informed about any contract. The only way I can get rid of it is cancel the credit card I signed up with. This stinks.
