Sharepoint site templates

When creating a new sub site in SharePoint, you can restrict users on what kind of site template they can use to create the sub site.

You can specify which individual site templates users can see when they create sub sites, for instance you can enable just the publishing site template so that all subsites are of type publishin site.

This option can be set by modifying the Root level site settings and choosing the option "Page Layout and Site Template Settings" under the heading "Look and Feel".
