Milestones are great for keeping track of important dates or project updates.
From the People view of the Timeline, they appear as colored dots that can be hovered over to reveal more information.
From the Projects view of the Timeline, they display across from the project name on their assigned dates.
You can edit existing milestones directly on the Timeline in both views.
To create a new milestone:
From the Projects view on the Timeline, click a date next to the project name for which you want to create a milestone.
From within an individual project's details on the Manage page, select the Milestones tab.
