MeetingHand allocates a sub-domain for your event during your initial setup. This sub-domain is created with the short name of your event.
You can always change this subdomain but please note that your subdomain can only be 18 characters long.
Important Note: Once you update your subdomain, your older domain will no longer be accessible.
To edit your subdomain, go the Event Settings, then Web Page & Banner Settings and click on the Edit Domain button, then type your new domain.
