Before requesting a specific Domain Name you may
want to first research the free, Web-based interface located here. It
is particularly important that the person in charge of your organization's
corporate image approve the choice of subdomain name. It is your
responsibility to ensure that you have the right to use the domain
name you have chosen.
You may mix upper and lower case, or use all upper
or all lower case. Software will ignore case and users can type
in whatever case they like. You should capitalize your subdomain
name as you wish it to appear in machine generated lists, such
as the return address generated in your outgoing electronic mail.
Hyphens may be used to separate words if necessary or consistent
with normal references to the proper name of your organization.
