You are the SharePoint administrator for a company. You plan to deploy the SharePoint sites that will be accessible from the company portal. You create the following sites:

A user named User1 will manage the sites. You must prevent all users except for User1 from creating sites and subsites. User1 must be able to delegate management of List permissions to other users. You designate a user in each division as a lead for that division's site.
You need to allow the designated lead in a division to manage their division's site while minimizing administrative effort.
What should you do?
