Hello, Currently Debian Wiki (wiki.d.o) is run on MoinMoin. I proposed migration to MediaWiki, which is most deployed wiki application. It is used by Wikipedia and FANDOM.COM.
AFAIK, MediaWiki's features are: - Searching through logs. This feature is thrown when user search for non-existent articles. - User Talk, similar to comments on blog. Unlike comments, User Talk has its own page, related to corresponding article. - Articles can be edited anonymously (without logging in). - Content Licensing. During installing MediaWiki, license for wiki contents can be selected, perhaps the most popular is CC-BY-SA 3.0. Thus, footers on wiki site contains "Contents are licensed under $license". - Page Templates. This can be form of notes or warnings. Let me know for any technical issues.
