TeamForge allows users to easily associate, or link together, any objects in the system to simplify knowledge sharing and provide traceability throughout the lifecycle.
For example, a discussion post regarding a customer problem could be linked to a document specifying the feature requirement. An issue might be created to track the defect, the source code commits that fix the issue, and the release that contains the fix. All of these records can be linked together with an association. When any item is associated with another, the link appears on the item's ASSOCIATIONS tab.
Associations enable development organizations to improve information sharing, capture institutional knowledge, and simplify regulatory compliance.
An option is provided at site level and user level to make sure whether the notification mail has to be sent or not. For more information on this, see Configure your site's settings.
