From the Project page a user can:
Selecting this button pulls in the changes from the mainline.
Selecting this button runs classification against the project.
Selecting this button runs validation against the project.
Selecting this button promotes the project to the mainline.
All tasks within a project are listed here, and a tooltip is displayed for each task's name link in the list, however the task can only be opened from this view by the task author (ie the owner of the task). So authors can only open their own tasks from the name links in this listing - for any other author's tasks, the name link will be inactive.
