More often than not, we may need to change the name servers for multiple domains and within the interface it is very difficult to do this as quick as you want to. First you need to go to the home page, search for it and them go about it. Here’s how I found a solution.
http://manage.resellerclub.com/servlet/JumpToDomainServlet? productCategory=domorder&domain=<yourdomain.com>
Obviously, replace the ‘yourdomain.com‘ with yours and make sure that you are logged in. This would obviously bring up the domain management page and you can get to work right from there.
Hope there’s a better one!
