Notepads, sticky notes, and the palm of your hand make for fine ways to take down notes about a project.
Project notes in IPIN are better.
Project Notes are located beneath the Scope of Work and Project Location on the Project Details page of every project.
They are company specific, meaning only people logged in under your company account can see the notes. This makes them useful for communicating on projects with co-workers, especially if there are multiple employees in the same office with IPIN user accounts.
Searches can also be run for projects using keywords from your notes.
