There are several ways to create sub-user accounts:
(1) You can ask users to sign up DriveHQ accounts themselves. This saves a lot of administration work.
(2) For those who don't want to (or don't know how to?) create accounts, you can help create accounts for them. You can just sign up a new account for them using their email address. However, the users will have to activate their accounts.
(3) You can order our Group Service plan, which offers you a comprehensive group administration tool. You have full control of sub-user accounts, incl. creating/adding/editing/deleting sub user accounts, allocate storage space and bandwidth, etc. Group service has an additional charge of low $6/user/year.
Group service is currently only available to DriveHQ Support team members. It will be availabe to all users in early Sep. Stay tuned.
