How can I switch to manage another domain?
On the left hand menu in the Manage Another Domain box you'll find two buttons, Find Domain and Select from list.
- To switch directly to another domain, type in the name (it must be in the same profile that you are logged in for) in the space provided and click Find Domain.
- To select from all domain in your profile, click the Select from list button. A listing of all domains in your account will appear. Simply click on the name you wish to manage and your profile will switch to it.
