There's lots of freeware out there (though generally this assumes you have a web server to run it from): http://en.wikipedia.org/wiki/Comparison_of_wiki_softwareDomain hosting is pretty cheap though if you haven't given in yet - we have one with HostMonster (http://www.hostmonster.com/), which has a couple of these freeware solutions basically set up (you just need to click to install one and your are up and running).In the past, I've played with TikiWiki (http://info.tikiwiki.org/tiki-index.php) on the HostMonster domain and it had a lot of functionality possibilities, but was clearly still a work in progress with many features not fully working, but I haven't tried the newer versions. Depending on what you want, it could probably do the trick.I'm no expert, but email me if I can be of more help (Dan, you know how to get in touch).
