Thread:Project:Support desk/Getting started as Admin (user rights)/reply (7)

The according video shows MediaWiki 1.14 and the user shown there is in the admin and bureaucrat groups. The preferences page shows exactly that (second 39) and in this version MediaWiki obviously showed a link "User group rights". This page can be found as a page in your wiki at Special:ListGroupRights. Access to this page is not restricted to any special user group - even users, who are not logged in can view it.

Settings should always be made in LocalSettings.php, not in DefaultSettings.php. Note that these file names are case sensitive (so it is not defaultSettings.php).
