History of this wiki
A previous version of the wiki, in Wikispaces format, was hosted on sourceforge.net. The content was then migrated to a new wiki in MediaWiki format, and the old wiki was decommissioned. During the migration, in order to avoid excessive downtime, we moved the content to what was intended to be a temporary wiki on wikispaces.com. However, since it was significantly faster than the MediaWiki hosted on sourceforge.net, we have made it the official permanent Weka wiki.
