In this posts I am going to show you how to create a very popular and efficient download system on your website. The concept is simple: users will be required to tweet (a message of your choice) before being able to download files. This is a great system for going viral on the social networks and promoting your website when offering freebies, for example. A lot of freebies websites use this system. As you may have noticed, we use it too, here on DesignerHype.
