Wiki's-Big on Collaboration

I've been using Wiki's for a while now and I really love them. At my work I have several running to help in P.D for my fellow colleagues. I really think that help to save time and fuss when you need to co-rdinate a big project or you are just working with a large number of people. This is great news when you are an educator and you need to communicate with students when they are miles away. I think we need to use this tool to its full potential and collaborate to the max!
