Can I watch or follow a backlog item or task?
Yes, you can watch a backlog item or task to get notifications about what happens in the backlog item or task. To do so, open the popup dialog for the backlog item or task, click the "More" link in the lower right corner of the dialog, and then click "Watch this item" or "Watch this task".
When you're watching a backlog item or task, all activities that happen in the backlog item or task will appear in your notifications. You will also get email notifications about comments and attachments added, if you've enabled this in your personal settings.
