"Accounts" are referred to in several places in the panel and I'm not positive which you're talking about.
(Billing > Manage Account)First, you can own more than one account at DH - just as long as you sign up for them through your panel. You're not allowed to use a promo code or refer your self obviously. but if you need more stoarage space or whatever you can sign up and pay for an other account.
You can also (Users > Account Privileges) allow other people to access parts of your panel. For instance you may decided to host a domain for a friend, you can set them up with a panel log in that only has access to their domains (E-mail, mysql, etc.) and none of your domains or the billing section.
There also used to be a place in the panel that referenced what account you were currently logged in as - though I don't see that now in my panel, for people who manage multiple accounts for clients.
Hope this helps.
