View source for Privacy

You can set wikis up in different ways
* completely private - invisible except to registered users
* a bit private - only editable by registered users, but viewable by anyone
* more public - anyone can register and add stuff

You can customise them (or set user permissions) to remove some of the complicated gubbins.

This one is on my web server, but a bit private.  You could have one hidden away inside your firewall.

The [http://www.pontneo.com/ctf/ {!ctf} extension] on this wiki records the clicks of registered users.

"What's Popular" on the main page and "[[Related Pages]]" on others don't need to know who clicked, just that someone did, but "[[Personal Recommendations]]" needs this information.  

Knowing who clicked what when can also be useful for personalising things like search.  For example, if you're an oncologist searching for "pain", you might want oncology type documents at the top, rather than scrolling through a lot of stuff about ibuprofen for dentists and back pain for GP's.  I didn't bother with this here, although the {!ctf} engine does this sort of thing if you want it.

I think it's worth mentioning two things about privacy in this context;
* this is exactly the same traffic that is already recorded in your own and many other server logs
* something like a wiki is by definition a public space, like the atrium, not a private one like the loo's - learning the difference is an important part of digital education.
