Create Different Access Levels for a Spreadsheet
You start by creating different levels of access to a spreadsheet. For each level, you will tell which tabs can be accessed by users belonging to it.
Register Users, their Passwords and their Access Levels
Whenever you want, you can add new users to the spreadsheet or delete old users. Registration always uses a username, password and the choice of an access level for viewing specific tabs of the spreadsheet.
