 As each new version is saved, it is viewable from the rest of the Internet and prior versions can be retrieved in cases of error or change of mind.It is notable that this Wiki style of evolving web content extends to all the textual, graphical, and scripting content in Lively, as well as to any new forms that may be defined, yet without any need for a Wiki server of any kind.All that is required is a server providing a HTTP WebDAV interface.
