There are several sections throughout Broker Brain that allow you to store notes, and all of them function the same way. The Notes section within the General Inspections tab was designed to give you a place to store pertinent information about each inspection. You can create and store notes, attach documents, and send out emails from here.
There are two types of notes you can add into General Inspections:  General Notes and Inspection specific notes.
When you initially click the General Inspections tab, the following window will appear at the bottom of the screen.  This window is meant for general property inspection notes:
To add notes specific to a particular inspection, use the Notes tab from that inspection's window.
