How to protect MediaWiki so only registered members can post?
By default anyone can post and edit articles in MediaWiki. If you want to set up MediaWiki in a way so that only registered members can post, you will have to make the necessary changes in the LocalSettings.php file. The following line:
$wgGroupPermissions['*']['edit'] = true;
should be changed to:
$wgGroupPermissions['*']['edit'] = false;
