Disregard; I mis-understood the question.
I really like this. We are just in the process of looking at a way to make better use of the FAQ function in WHD. This will be a great help in that. Thanks for sharing.
Currently, in WHD, FAQs can be created by a Tech either directly in the FAQs tab or from a Note that the Tech is entering into the ticket. In either case, when saved, I believe the FAQ will be in a non-approved state. An admin would need to - at some point - go into the Tech side, go to the FAQs tab and do a search for "non approved" FAQs. They can then review/edit them and then check the box in the FAQ for "Approved".
I don't believe there is any current functionality to auto-notify or do back and forth in-progress dialog between the tech and admin users...it's just FAQ is Created - FAQ is reviewed and approved (or not).
