[Mediawiki-l] Talk pages on MediaWiki

[Adrian Overbury]

Hello.  I'm currently assisting in the setup of a MediaWiki 
installation, and the project owner has asked that we find a way to 
disable all talk pages on the wiki.  I had thought to assign all talk 
pages to a category that only sysops could edit, but i thought better of 
this on reflection, since it would involve coding an extension for it, 
and it would leave a lot of void links around the place.

The links lead me to my next idea: removing all the links to the talk 
pages so that no one can access them through normal means.  So, I have 
to ask, where are all the references to talk-page links?  I managed to 
remove the 'my talk' and 'discussion' links for the header and body of 
the 'recent changes' page, but that's about it so far.  I've commented 
out several other references to them in SkinTemplate and other pages, 
and even tried turning the 'talk' and 'mytalk' references in the 
Language.php file into null strings, but to no avail.  So, where does 
MediaWIki build the 'discussion' and 'my talk' links in normal article 
pages from?  Do you have any other suggestions as to how I could achieve 
this?

Addendum: From what I've seen, I've actually managed to remove them from 
most namespaces, but the namespaces like NS_MAIN continue to have them. 
  Are these pages generated somewhere else entirely?
