Originally developed in 1994, a wiki is a collaborativewebsite
which can be directly edited by anyone with access to it. This episode
discusses, how and why you would want to use a wiki with your classes.
Wikispaces - Hosted wikis ad-free for educators (this site is a Wikispaces wiki)
DokuWiki
If you'd like to install your own wiki software, you might want to try
DokuWiki, as it's simple to install and use. It works on plain texts
files and thus needs no database.
