One of the new features in SharePoint 2013 is the ability to create and publish site policies . Essentially, a site policy defines when a site should be closed and when it should be deleted, together with any reminders, workflows, and so on that you want to associate with the process. You create site policies at the site collection level, and you can then publish them through a Managed Metadata Service application to make them available on other site collections. One of the big selling points of site policies is that you can use them in conjunction with self-service site creation. The basic idea is that you allow people to create their own sites, but mitigate the associated risk of site proliferation by forcing them to select an appropriate site closure and deletion policy as part of the site creation process. This is all well-documented elsewhere, so I don't plan to go into it here. Instead, I want to focus on a couple of specific issues that stumped us for a couple of hours.
