Don't use mistforums, worst mistake ever, if you're looking for free sites use enjin at least they have more security than mistforums would ever have :v

http://yoursite.mistforums.com/admin > Domains > Add domain > Get nameservers > Change nameservers on host

Also, MistForums probably isn't the best forum out there.

lmao mistforums

You're better off with MyBB or Enjin.
