Cooperation with google docs

When planning English lessons, I always cooperate with teachers who teach the same course as I do. We agree on topics, but we also create detailed lesson plans and various activities together. Thanks to google docs we do not have to sit together in the same room to do this. Nor do we have to send each other numerous versions of the same documents. In google docs we can edit simultaneously and to me, this is perhaps the most useful discovery of this school year. Google docs is, of course, free and all you need to create an account is your e-mail address. Go to: http://docs.google.com
