Intertiki is turned on now, which makes this site a "slave" to the master, tikiwiki.org. That is, users registered at tw.o automatically have certain preferences and their group memberships when they log in here. This is a neat and powerful tool, and should continue to get fine-tuning.
This site is to showcase how the different Tiki features look and function in various themes, so the menu now lists more of these features. Content will be added at the end of those links as time permits.
