Activities in TeamForge Orchestrate often have associated detail pages that give more information about the activity, the ability to comment, and to view associated activities.
For example, a commit detail page has information on the SCM repository name, the committer information, commit comments, files affected, etc. The detail page also has an "Associations" section that shows all activities and TeamForge work items that are associated with it.
Note that external activities do not have detail pages but instead may link to an external URL.
