You have questions regarding Weka?

You can post questions to the Weka mailing list. Please keep in mind that you cannot expect an immediate answer to your question(s). The questions are mainly answered by volunteers, Weka users just like you.

You are looking for packages?

With Weka 3.7.2 and later, you can easily install packages through Weka's package manager interface, either official ones or unofficial ones. Have a look at the Packages article for more information on this topic.

You want to contribute to the wiki?

The wiki is based on Markdown articles, which are turned into static HTML using MkDocs (see here for details on writing articles). The content of the wiki is available as repository on GitHub. Feel free to add/update and then do a pull request.
