Wiki . . huh?

So I thought I was pretty computer savvy. However we are learning about wikis. I knew about Wikipedia but there is so much more to it than just that. We can create our own wiki for a classroom, we can edit wikis. I am finding out quickly that not just anyone can go edit a wiki they have to have approved information by the administrator and an actual wiki account. It's a growing information system. It's a great way to learn from each other.
