• Let individual site administrators become more aware of the site settings administration options that are available in each site.
• Enable usage analysis processing to get a better idea of how sites are used and which ones are more popular.
• Consider the use of auto-site deletion for stale sites to reduce the overhead on the environment generated by unused sites.
• Use the IIS Manager tool for SSL certificate generation and to change authentication settings on individual IIS websites used by web applications in SharePoint.
• Use PowerShell for command-line administration, and only use the legacy STSADM tool for specific scenarios when legacy command-line functionality is needed.
• Review the powerful options in the PowerShell or the STSADM command-line tool, but be cautious about using them because they do not warn before making changes.
