Not sure where exactly this should go, I started my project under a subdomain of one of my domains, then later changed it to a new domain name. The original domain (the subdomain) is registered with the community as the master, while the new domain is also registered and listed as a stage.

Is there any way to remove the subdomain from the list as it is no longer there?

Also, what exactly is the difference between the "master" and "stage" types?
