This is a list of tips and tricks I use on various WikiMedia that I run.
Unless noted, this applies to the 1.15.1 – 2009-07-13 version.
On Laussywiki, you can't follow a red-link (that refers to a page that still does not exist). If you try to force your way, you will be blocked by login permissions. But normal users do not get distracted in opening a page that tells them it does not exist and that they cannot create it. The link, however, exists, to inform it will/should appear at some point.
This is achieved by patching Linker.php, c. Line 287:
# Get a default title attribute. if( in_array( 'known', $options ) ) { $defaults['title'] = $target->getPrefixedText(); } else { $defaults['title'] = wfMsg( 'red-link-title', $target->getPrefixedText() ); if ( $wgUser->isLoggedIn() ) { $defaults['onclick'] = "return false;"; } }
