To be precise, we only give away one Frihost subdomain for each user, like something.frihost.org or something.frih.org.
However, you can add your own domains and make subdomains from all the domains in your account, including the subdomain you got from us. Like sub.domain.com or sub.something.frihost.org. What isn't allowed is a second Frihost subdomain, like something2.frihost.org.
So what if I wanted a subdomain change (which I will shortly), but I wanted the old sub to stay active for say... 30 days. Purely for 301 redirect purposes and retaining traffic. Could something be worked out there? Or will I just have to accept the domain change without a redirect and take the hit to my traffic?
Also, I won't be using .tk, the popup adds are annoying. If I was to do anything like point another domain at the name server I'd grab one from dyndns or no-ip.org. The thing is I'm wanting to point my "old" .frih.net domain to my "new" one.
