[Mediawiki-l] Security in Special Pages. How can be done?

[Fernando Carpani - INCO]

Hello.
I'm using PageSecurity on Mediawiki 1.9.1 with postgresql... and 
works.... (to me :-) )
But, in my security scheme, I need public pages (readble for anonymous 
user) and private pages (readable and writable for some groups). This 
works OK with articles but I need control some special pages in the same 
way. For example, Listuser... I don't want that an anonumous user can 
see the user list... (or specialpages)...but  I want that some groups 
(or logged users) can use this pages....

How can be done this things?

I'm learning about hooks, and extensions, but.... the hook apropiated 
for that (until I can see... ) can restrict the list of  Special Pages 
or  Query pages.... but if someone knows the url can execute them...
I suppose that can limit the link generation, but someone can invoque 
the page with the URL....Obviously, I'm not an expert in PHP but... I'm 
trying to learn :-)
Someone has any development over this things?  I'm undertstandig the 
mechanism... or I'm loose in a sea of php files... I dont know? someone 
can guide me?

Thanks.
