*  Zope provides the ServerSide architecture for storing tiddler content and constructing the TiddlyWiki frontend for the client. And with FreeZope, even cheapskates can have their own ZiddlyWiki!
    * ZopeAuthentication is used to track and restrict wiki content modifications.
    * ZopeRevisions store old tiddler versions, and ZW makes use of this feature to provide TiddlerRevisions.
    * AJAX is used for all after-page-load communication with the server.
    * TiddlerLocks prevent several people from editing the same tiddler at the same time.
    * AutoRefresh keeps the page up-to-date without requiring a reload.
    * ImportAndExport allows you to take your ZW offline wherever you go. Even better, you don't have to commit to ZW -- take your data with you when you're done!
    * MultipleZWs allow you to have many sites without the hassle of uploading ZW multiple times and maintaining each one.
