Odoo brings social networking concepts into your business communication. Fundamental to this implementation is that you can get automatic updates on a business document by following the document. Then, whenever there is a note, action, or a message created that is related to a document you follow, you will receive a message in your Odoo inbox. In the bottom right-hand corner of the form, you are presented with the options for when you are notified and for adding or removing followers from the document.

The checkbox next to Discussions indicates that I should be notified of any discussions related to this document. However, I would not be notified, for example, if the stage changed.
