In the initial stages of the project, it allows you to post functional specifications and post project related documents (like meeting minutes, client proposals, etc.). As the project progresses, it allows you to post baseline documents (like detailed designs and project plans). As development proceeds, it allows your testers to track test cases and software defects. Developers are automatically alerted, by email, as defects are assigned to them. Team members are alerted as new documents are uploaded or re-uploaded (like project plan updates, etc.). And each person has the ability to control the email alerts they wish to receive.
