Good! This one will last better than batkins' Tk Wiki which was spammed to smithereens.
That's precisely why I didn't go with a regular wiki. I still receive some spam inquiries via www.perltk.org every now and then, but it's manageable.
I'm curious about which engine you are using to drive the website ...
I'm using
Mambo. Recently the core developers of Mambo branched off to create
Joomla. Mambo/Joomla is really nice for people who don't want to spend a lot of time tweaking the website. It satisfied my needs. Many people complain that it does too many things. It really depends on how much experience YOU have, and how much time you can afford to spend tweaking the look of your website.
Another, much simpler and IMHO much more elegant, CMS is
Drupal. If I had to do things over, I would go with Drupal.
