From the HQ screen, you can control what users have access to the database and whether they have administrator privileges (access to the HQ).  Additionally, you can tailor all relevant pull down menus throughout the database to your particular needs. Note for database integrity reasons, you do NOT have the ability to delete fields from these pull down menus but you can change them. The fields are populated with 'generic' items and are not meant to be all-inclusive.  You can change them to your liking or add additional items for each pull down menu in the database.
