Nick, What do you want to be able to do?
Do you have a server if yes do you want to set your nameservers? if yes follow these instructions
In your account click on your domain name in the next window you will see DNS SERVER to set to your custom server click configure, then add in your nameservers
ex: NS1.namepros.com
NS2.Namepros.com
If you do not have a nameserver i would suggest you get some hosting for your domain, If you need some space let me know i can hook you up.
If you just wanted to have your domain point to another website already online just click the DNS SEVER area again and make sure the nameservers are set to
dns1.name-services.com
dns2.name-services.com
dns3.name-services.com
dns4.name-services.com
after ensuring these are set then just go to DNS SETTINGS (FILE ZONE)
and set these
* (other) URL www.(whateversiteyouwanttopointtoo.com)
@ (none) URL www.(whateversiteyouwanttopointtoo.com)
www URL www.(whateversiteyouwanttopointtoo.com)
Other than that your question was vague ....Good luck
