Well, I did it. I found a Wiki and I got it onto our server. I've now started writing material for it and I must admit it works quite well. The only problem is that the server we are using is a somewhat elderly Linux box (apparently the best Wiki in the world works best on Linux), You can see what I've been up to by going
here. I think that the format works well.
But we are going to have to find a faster machine.....
