The Administrative menu is where you will add, edit and delete users, locations, groups and reports. These are the people, places and reports that work around the Standard Operating Procedures that you have defined. This window is accessible from Administration > Users.

The Users tab will be the first of the 6 tabs that you will see. Each tab will show a list of pre-existing users, locations, groups, reports, server, and external contacts. Each tab will offer you the option to Add, Delete or Edit the items listed in its panel.
