As the project owner you can change your subdomain by going to Configuration > Project Settings and scrolling down to the bottom until you see this button:
Type in your subdomain, then hit change subdomain. As long as it's not taken you're good to go!
If your requested subdomain is taken, you'll get an error message. Please email [email protected] to check if it is an active account, or if we can free up the subdomain for you.
