Tinamous has been designed with the idea of dedicated accounts. You can have numerous users and devices in a single account. You can create accounts for your home automation, office communications or even project specific accounts.
When you create an account, you get your own account specific sub-domain of Tinamous, e.g. if you registered 'Office' as an account name you would get 'Office.Tinamous.com' as your dedicated account area.
Because accounts are separated by sub-domain, a user can join many different accounts with the same email address; however that user will only see the feed from the specific account they are accessing.
When you create an account, the user account you create at that time becomes the administrator of that account.
