Try Before You Install

You can play with a fully functional Tiki demo, hosted by opensourcecms.com, before you install Tiki on you server. Try it out now.
Additionally, you can download an iso of the tw:TikiLiveCD, version 1.9.11 or 2.0, burn a CD (or use a virtual machine with it) and play with it.

Work has already started on TikiWiki 3.0, which will be released in April 2009. The main focus of version 3.0 will be further enhancements to the user interface, the admin interface, the theme system and built-in themes.
