When referring to accounts in the context of our href="/solutions/ssd-multi-account">SSD Multi-Account plans, we refer to the separate login you have the ability to create within that package. However, within each account you create, you can host as many domains as you desire, as we have no hard limit on them (although we do not recommend more than 10 due to the increased difficulty in managing multiple domains within a single account). If you're a reseller, you can even limit and create your own "shared" hosting packages for your end-users by limiting the number of domains they can put within a single account.
