Post by KimIs is possible to hide Sharepoint Themes so that a user
cannot change the Theme of their site?
You can certainly suppress themes from the list of available ones. The
control file is \Program Files\Common Files\Microsoft Shared\Web
Server Extensions\60\TEMPLATE\1033\XML\WEBTEMP.XML (so you'll want to
make a backup of your original one first ...!)
Open WEBTEMP.XML and change the Hidden attribut to equal "TRUE" for
the templates you don't want to appear in the list.
