Tikiwiki as a "secure" wiki?
One of the biggest questions I get from people who want to use wiki.ucalgary.ca is "How do I protect or lock a page?" I've had to respond with a gentle suggestion that the wiki is an open resource by design, but that doesn't go very far. There are valid reasons for locking down a wiki - ranging from sensitive information that shouldn't be In The Wild, to protecting privacy (K-12 collaborations can't have info about kids leaking onto the 'net for obvious reasons).
