DefaultUserTheme

This setting controls which theme will be shown to users by default when logging into the main IBPMExpress portal. Themes may be hard-coded for items served in other contexts such as Content Server Web Parts that use the SharePoint theme. The theme name maps to a directory name under the IBPMExpress install directory, which is typically stored at c:\Inetpub\wwwroot\IBPMExpress\Styles\[Theme Name].
