Thread:Project:Support desk/Is it possible to restrict user from all the Special Pages and Recent Changes Page??/reply (2)

CSS is extremely weak for this. If the person knows the special page name he/she can enter the URL directly on their browser's location bar, or use the search.

There's no core MediaWiki functionality to do this. Maybe you can extend MediaWiki using a hook to check if the requested page is a special one and if the user is not in a specific grup prevent the action. Note that data in some special pages can be accessed through the api anyway.
