I have a website hosted on my server at work. I am thinking of setting up a fairly simple wiki on the site. However, I'd like to make it so that each of around 100 people (students in a school) can login and create their own wiki. So technically I guess it wouldn't be a wiki, as I only really want each student to contribute to their own wiki. But hopefully what I want to do makes sense. Could someone point me in the direction of either some good (free) code designed for this, or else some pointers for the steps I'd need to take to set it up myself.
Many thanks
