Subscribing to a document allows you to receive email notifications informing you of any changes to the document. These changes include, classification changes, field value updates, workflow movements, and comments added to the discussions tab.

Subscribing to a document also allows a quick way to access the document in Nucleus One. On the dashboard, you can add a Subscriptions widget which lists your four most recently subscribed documents. The widget is a shortcut to the Subscriptions page which contains a full list of all your subscribed documents. You can also access your subscriptions through the main menu in the top left corner of the page.
