This is hardly the most exciting part of GPS Insight, but most customers need to know how to add users, restrict them to only certain vehicles/permissions/landmarks, etc.
Here is a 15 minute demo I placed out there today on how to add a user (in this case a real world new user for our account).
The demos are very useful, and we try to keep them up to date. They take a while to watch, but they walk through most capabilities of GPS Insight and the longer ones have a table of contents to skip around.
Enjoy!
