Wikia just closed the German Code Lyoko Wiki: de.codelyoko.wikia.com . I'm working on getting a database dump of that one. Nobody has informed any of the users why this has happened. We suspect it was a mistake.
Out of fear that this could happen to other wikis in our network, I'm advising all of the Code Lyoko Wiki leaders to make independent backups of the wiki, and I'm making backups of the wikis I have admin rights on.
