Steps to add a custom domain to your account

1. Create a new CNAME entry using your DNS manager. Pointing xyz.mydomain.com to the Geckoboard load balancer geckoboard-1512102130.us-east-1.elb.amazonaws.com where xyz is the subdomin you want to redirect to Geckoboard
2. In the "Your Details" tab of the Account screen you need to update the "custom domain" field with the subdomin you chose. E.g. add xyz.mydomain.com
3. Now all your read-only links will be available from this domain. E.g. If you have a read-only dashboard with the URL http://myaccount.geckoboard.com/dashboard/B6782E562794C2F2/ you can now reach it at http://xyz.mydomain.com/dashboard/B6782E562794C2F2/
