Hello,
I know there is a page called Picard Plugins (http://wiki.musicbrainz.org/Picard_Plugins)
So what I do is :

1. I'm typing wiki.musicbrainz.org/picard plugins
2. I arrive here : ''page empty'' http://wiki.musicbrainz.org/picard_plugins
3. I click ''search for this page title''
4. It now says ''There is no page titled "picard_plugins". You can create this page.'' http://wiki.musicbrainz.org/Special:Search/picard_plugins

It should have found http://wiki.musicbrainz.org/Picard_Plugins

Here is how I can never find anything in the new wiki. I should use the search box, it works.
