El caso es que no puedo añadir mi dominio porque lo gestiona Google apps y tengo que hacer una serie de pasos que no entiendo :ambivalence:
"If your site is not currently CNAME'd to ghs.google.com, the association of your domain with these Google products is probably a dangling entry. You can delete it using the following steps:
Log into Google Apps with your domain name and the section as Domain Management.
Once you login, navigate to the Dashboard tab.
If your site is associated with Google Sites, click on the Sites service. This should take you to the Sites settings page. In the Web Address Mapping tab, your domain, say
IANA — Example domains, should be listed as a mapping. Find this mapping and delete it.
If your site is associated with Google App Engine, click on the associated App Engine service under the Google App Engine section. This should take you to the application's settings page. In the Web Address section, your domain, say
IANA — Example domains, should be listed as a mapping. Find this mapping and delete it.
Wait for at least half an hour and then press Continue on the Console to proceed to the next step."
