["DebianWiki"]
The DebianWiki engine has changed from ["ZWiki"] to ["Kwiki"] (see the ?UpgradeNotes).
But I suggest change to [http://wikipedia.sourceforge.net MediaWiki]. With MediaWiki we can manage more easily categories, pages in different languages (the interwiki links) and so on.
I have never used MediaWiki, and so it's hard for me to say one way or another. If/when the wiki becomes official, and is on Debian hardware, it might be time for a discussion about wiki software from whoever will be maintaining it, but for now, Kwiki it is.
