making a wiki page ...

So anyone can make up a wiki page? I never knew. This idea is very cool and I think that my colleagues might be interested ... we could make a wiki page for our school. We have a website but it might be an idea to also have a wiki page where the teachers can add information ... a cooperative approach. We would have to make sure that there were strict rules as far as allowing only staff to contribute for the most part. Shall have to speak with the prinicipal.
