[cobalt-users] Subdomain on a subdomain (3th level domain?)

["Superior Webhosting Technisch" <tech@xxxxxxxxxxxx>]

Hi!

I would like to add a subdomain to a subdomain. I think it's called a 3th
level domain, like:

users.subdomain.domainname.com

How do I add this to the DNS server using a RAQ2 ?

Thanks!
