Scenario/Problem: Earlier in this chapter, you saw that to assign permissions to users or groups, you can choose from a predefined list of permission levels, such as Readers, Contributors, and Approvers. If you want to create a permission level that differs from the existing permission levels, you can create a custom permission level. For example, you might want to create a permission level that enables users to view and delete items or files but not edit them. Or maybe you want to create a permission level that allows users to view the site and be able to create subsites but not edit items in the site.
