When you register an account with Comster you are automatically assigned a comster.com domain name, for instance mywebsite.comster.com. The domain name is created based on the email address you enter on registering.
You can easily adapt your Comster domain name under Site settings > Domain.
Under ‘Comster Subdomain’ you will see your current comster.com domain. You can change it to something more appropriate by adjusting the domain in the field. If the domain name is available, simply save the settings. Easy!
