"NO SERVERS" means that workgroups and teams do not have to get IT to install and support complex software on servers, and manage storage farms for managing your shared content.
With Content Circles, you collaborate right from your desktop and shared files in your circles get replicated across all circle members' computers. In addition to eliminating the need for centralized servers and storage, this approach provides 100% security, automatic backup, and offline access to all of shared files.
