Yesterday I read about JUG Milano's intentions to get more and more involved in the VQWiki project. As I've been searching for quite a time for the easiest of Wikis to just drop in my servlet container and start to edit, I decided to give it a try.
As a matter of fact setting up VQWiki is really straightforward: download zip, unzip, upload war and boom you're it. I haven't even started to scratch the surface, but what I've seen so far serves my purpose of having a site for the project we've just started - the simplest thing that could possibily work... well it works!
If you're a newbie with Wikis and want to experiment, VQWiki is a really nice start.
