How to make Notification?

Does anyone know how to make the Notification?

Where can we find this Notification functionality?

If you are talking about spy notifications, take a look at this off-site help guide:

http://www.streamhead.com/boonex-dolphin-spy-module-integration/

and AlexT gave some helpful info at this forum topic:

http://www.boonex.com/forums/#topic/Outline-help-request-for-BOONEX.htm

The last link talks about the Outline but at the end Alex also adds info about the spy notifications.

How to customize this spy notification?

Can you explain me?

If I wanna to implement this notification in my module what I do?

I can not provide step by step guide.  I suggest you do as Alex said and go to an existing module that includes notifications and study the script to see how it was implemented.  I provided two sources to help with understanding.  I am not a module developer.
