I have read that article, thanks
But couldn't understand this:
"Domains - Domains reside inside of user accounts. This is important to note as this is the reason that only one user has access to 1 domain. So if you wanted to have Ted, Bill & Rufus to have access to 1 domain you could only give 1 of them access to it or create a User account and Provide all 3 of them with the login information."
I can not host more than 1 domain on sub account?
