Getting clients and contacts on the same page when working on a project can be difficult, and getting everyone to use the same project management software is even trickier.  That being said, most people have a dropbox account, which is what makes Sitedrop such a welcome and innovative idea. 

Sitedrop allows the user to change a dropbox folder into a website that allows work sharing and collaboration with minimal clutter, and the ability view and comment.  Adding files is a simple as dropping a file or a link into a dropbox folder.  

Sitedrop is available for free right now, and gives you 5 spaces to work in.  The startup is still growing, and more features are on the way.
