Using MW 1.20.2, I've edited the TOOLBOX heading in MediaWiki:Sidebar with no effect
whatsoever in the Vector skin or other skins. Is there a setting needed to enable this?
Placing common links to test like this:
* TOOLBOX
** mainpage|mainpage-description
** Special:Recentchanges|Recent changes
does not modify the Toolbox links at all.
Thanks,
Al
