The HelpDesk ID will be used to create your own subdomain under smartanswer.com (e.g. acme.smartanswer.com)
and an auto responder email address (e.g. firstname.lastname@example.org). The ID may consist of lower case English letters
and digits only, may not start with a digit and may not exceed 20 characters. Once we set up your Help Desk, the ID may not be changed.
