Use Special:ExtensionDistributor to get a version of this extension that is compatible with your version of MediaWiki instead of using the trunk (development) version. --Jack Phoenix _(Contact) 08:54, 4 May 2009 (UTC)

require_once

being there are other readme firles in my extensions directory, i changed require_once('extensions/UserRightsNotif.php') to require_once( 'extensions/UserRightsNotif/UserRightsNotif.php' );. would this work for anyone else? Bud0011 07:01, 15 June 2009 (UTC)

Where to place the file UserRightsNotif.i18.php?

Hi I cannot fine any info where to place the mentioned file. The extension seems to work without problems without it. What is the role of that?
