In a preemptive strike against wiki spammers, our docunext wiki now requires a login. Chances are I'll be the only one editing it anyway! :-)
If you haven't visited it before, you can find it here: Docunext Tech Stuff Wiki
Kudos to Nanofortnight.org for helping me figure out how to set this up by adding the following to LocalSettings.php:
// Require login to edit$wgGroupPermissions['*']['edit'] = false;
