Thread:Project:Support desk/Show sidebar only to user who are logged in/reply

1.Make a skin that has no sidebar. 2.Edit LocalSettings.php so this new skin is the default skin 3.Make sure that new user accounts created after step 2 change their skin to one with sidebar Note that hiding the sidebar does not protect the functions as such. Users who know mediawiki will still be able to access the functions, sidebar or not. Some more info about this topic can be found here: http://www.mediawiki.org/wiki/Extension:ChangeSessionSkin
