I offer free zwiki hosting (with full manager access) on this server, as a gift and as a way to improve and promote the Zwiki engine. There's no guarantee of uptime, data integrity, or longevity of this service, but it has been running well for a few years now and you can export a snapshot of your wiki at any time. Your site will be running on the most up-to-date and actively-maintained zwiki server in the world, alongside zwiki.org.
See http://joyful.com for the current list of sites. Since the free wikis are public by default, be aware you will be indexed by search engines unless you restrict your permissions .
To request a free wiki, tell me your desired hostname, manager username, and something about what you want to use it for. (If it is just a temporary test space, use one of the existing wikis instead.) Inactive wikis will get retired. Subscribe to this page to hear wiki hosting announcements.

I am about to move all free hosted wikis to the latest ZWiki branch, to simplify hosting and get more testing. I hope you will not notice, please report problems to GeneralDiscussion if you do.
