The first tab in Tools>Options is User Information.
This is where
you enter your organization's name, address, phone numbers, etc. This
information is used throughout CMS when generating reports, invoices,
letters, default city and state for new entrees, and more.
Caution: Once you register CMS under an organization and a
password is entered, you cannot change the name of the organization.
Doing so will require a new registration password. When you try to
change the organization name you will get a message warning you of this
