You'll need to do that where you registered your domain name at. Did they send you a login url and a password so that you can set the nameservers? It should be pretty straight forward.
I believe so. I'll look through my emails.
Also, since I'm having problems starting the webdisk creator (port issues probably) should I just look through the other forums. I shut off McAfee firewall and added the ports to my router configuration to application forward for protocol TCP & UDP.
