Create a role first
In Team, the owner creates a role, chooses which menus it may use, then creates a sub-account. Team management and system management cannot be granted.
Fields for a new account
A sub-account needs a role, name, username, password, and the number of browser windows it may create.
A username is 2 to 30 characters, must be unique, and cannot contain spaces or < > " ' | \.
Edit the account or the password
The password is set when the account is created. Editing the account later does not show the password. Use Change password in the member list.
What the sub-account can see
A sub-account signs in with its username and password. It only sees the granted menus and the assigned window count.
