The theme should be useful for those who like the very nice Mediawiki/Wikipedia look and page functionality but want or need the more comprehensive feature set that Tiki CMS/Groupware provides.
Please see the README-FIRST file included in the download, or visit How To Add a New Theme and Customizing_Tikipedia for information on installing and personalizing the theme.
Any problems should be reported in the New Themes forum, along with other feedback or suggestions, which are welcome. Have fun!
