First set User Groups.
User Groups lets you give different users different Rights. You may want some users, such as GM's, to have Rights to all reciProfity functions.
But you may have other users who should only have the Rights to read recipes but not add invoices etc.
1. Click the Gear/ Manager Users & Units/ User Groups
2. Create different User Groups for different types of Users:
Give user names to the User Group
Pull down the arrow at User Rights
3. Check the Rights you want and click Save. If the User Group will have a lot of Rights it might be easier to click Select All and then uncheck the ones you don't want.
4. You can add new users to this User Group by clicking + New User on the right (but you will need to make sure you've already purchased Users/Connections first)
