Watch Issues
YouTrack lets you watch the issues you are interested in. You can also set another user as a watcher for an issue. When notifications are enabled for your YouTrack server, you and other users are automatically notified when changes are applied to the issues you are watching.
You and other users can specify which changes you want to receive notifications for on the Notifications tab of the profile page. For more information, see Notifications.
