You can point your domain at HappyPress, meaning that you can use a domain that you control.
Unless we are able to host your DNS records, we are not able to utilise an apex record (the domain without the www prefix, or any other sub domain) at present.
If you require the use of an apex record, you will need to create a redirect. This is not currently a service that we offer.
To point your domain at HappyPress, you should create a CNAME record with the value set as production-wearesmile-aws.eu-west-1.elasticbeanstalk.com
You should then notify your HappyPress contact, as some additional configuration will be required by us for this to function correctly.
