ElWiki

Description
ElWiki was a of wiki-based 'knowledgebases' on a variety of subjects. Users could create a wiki on any subject, free of charge, and get a free .com, .net or .org domain after hitting a certain threshold of activity. The owner of the wiki farm was Martin Rozinsky.

The site went in 2008, and is now a GoDaddy domain parker. People wanting to start their own wiki hosted by a third party should keep in mind that such disasters can happen.

Last message
From 21 February 2008: "We're sorry... We're sorry about the  we've been having lately.  Our previous hosting provider let us down.  We can assure you this was as frustrating to you as it was to us.  We've finally managed to migrate everything to a new set of servers.  The new infrastructure should be significantly more reliable.  We're still working on setting everything up, so some domains may be temporarily unavailable.  We're also closed to new registrations until we can ensure stability for our existing users.  -- The  team".
