The former JotSpot provided wiki hosting, aka a wiki farm. It included a blog, project management tool, bug tracker, and discussion forum. JotSpots wiki engine included a WYSIWYG wiki editor, e-mail integration, full text and attachment search, numerous other features, and also offered a behind the firewall wiki appliance.
JotSpot was taken over by Google, and existing JotSpot wiki sites were supposed to be transferred over to Google Sites, however, none seem to survive today. Original JotSpot sites will be available as an archive at the InternetArchive WaybackMachine at Archive.org.
