It's pretty handy ;) I should mention, to create a new page, you just put a link in any existing page. When you click the link, it will tell you that the page does not exist, and gives you the option to create the page. The great thing about the wiki is that it saves every single change that is made. To see a few examples, try this.... Open the wiki. Click the button in the top right corner that says "Recent changes". This page shows a list of recent updates to the entire wiki (very handy for keeping up with new stuff!). If you click one of the icons that looks like '3D glasses' - spectacles with blue and red lenses - it will show you the difference between the current version of that page, and the previous version. If you click one of the icons that looks like a sheet of paper, it will show you a list of the old revisions of the page. So as you can see, a vandal doing such a thing as messing up the pages, would be wasting their time ;)
