An addon domain is a
domain name that that points to a subdirectory within your account.
For example, you may want innovation.org.nz to point
to business.org.nz/innovation/. Addon domains must
be registered domain names that you own and configured to point to your
web site's servers.
To add a domain to your web site:
Click on the Addon Domains button
on the home page.
Enter the domain name in the New Addon
Domain field.
Add the directory that the addon domain points
to in the Username/directory name field.
Enter the password for the domain in the Password
field, if required.
