Who within your Organisation is going to be using Workbooks?  Make a list of who they are and give some thought to which areas of Workbooks you want them to be able to use.

When creating a new User you can specify:

• Which Edition and Extension(s) they can use.
• Which Own Organisation(s) they represent.
• Which User Groups they belong to (and thus what Capabilities they have).
• Which Databases they can access.

Users can be assigned records by using the "Assigned To" field within the different record form layouts; please note however that if this user does not have a valid license allocated to them, it will not be possible to assign records to them.
