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.
