Slideshare is an online system that allows people and companies to share PDF files, videos, documents, and PowerPoint presentations. It's widely used by businesses who want to make conference presentations available to customers online, and is ranked as one of the top 200 most popular web sites in the world.

Slideshare has always offered free accounts, which allow access to basic features. "Pro" accounts, which started at $19 per month, gave you more features, as well as being able to keep track of who had viewed your presentations.

Now, 4 years after the company started charging for Pro accounts, the fees are being dropped. All of the premium features will be free from now on. So if you run a small business and you want somewhere to host sales material which is more professional than Youtube, check out www.slideshare.com for details.
