Howto make Mediawiki users sign up before editing pages

If you want people to sign up before editing the page, which makes sense for preventing the page of being spammed, you have to edit the

LocalSettings.php

file in the wiki root folder. Have a look at the

./config/DefaultSettings.php

file, where you can find a number of default settings. All those settings can be overriden in the above mentioned LocalSettings.php file.

In order to prevent "anonymous" editing, add

$wgWhitelistEdit = true;   # true = user must login to edit.

to your LocalSettings.php file. You can find a complete list of configurations [here (http://www.mediawiki.org/wiki/Help:Configuration_settings)]
