Subdomains deprecated? How to turn off

So if they are deprecated, I can’t find the setting for the life of me to turn them off. My virtual server users get the option of creating a subdomain when they create a new virtual server.

Yeah, it’s disabled by default on new installs.

You can disable it on your existing install by going into System Settings -> Module Config -> Advanced, and in there you can tweak "Allow creation of sub-domains".

Doh. Didn’t see that. Thanks!
