Collaborative software (also referred to as groupware, workgroup support systems or simply group support systems) is computer software designed to help people involved in a common task achieve their goals. It is usually associated with individuals not physically co-located, but instead working together across an internet connection. It can also include remote access storage systems for archiving common use data files that can be accessed, modified and retrieved by the distributed workgroup members. In this article I have collected 10 very useful online collaboration tools that can help you be more efficient.
