I am trying to go from the 1-domain biz plan to the 3-domain biz plan. If my current 1-domain biz plan is listed as 'johndoe.com' and I go to 3 domains, I assume johndoe.com is converted to an "Addon Domain", and I can create and name the remaining 2 "Addon Domains" at a later time thru the cPanel without Rocken's assistance?
