I have 2 more sites that are registered through godaddy and I want to point them to Voda where I have my current SOHO site which is www.safersecurityproducts.com. I know I have to change the name server and I know how to do that.
Do I use the same name server as my current site?

I think that is what I did before and then add them in my cpanel. then build the new sites with the Voda builder.
