Deleting or Renaming the Home Item

When beginning a new project, developers sometimes delete the /sitecore/content/Home item in the spirit of "starting from scratch." While this impulse makes sense, it should be avoided in the case of the Home item. Sitecore uses the Home item for system-related features and configuration changes are required if the Home item is deleted or renamed: http://sdn5.sitecore.net/Articles/Administration/Configuring%20Multiple%20Sites/Adding%20New%20Site/Internal%20Links/Case%201.aspx

If you would like to rename your Home item, an easier solution may be to simply change its Display Name. To do this, click on the Home item, then select Display Name in the Rename chunk.
