Google Docs

Our group is just getting started using Google Docs for our PBL project. I used Google Docs in another class but it was fairly limited use and it seems to me the Google Docs has a different feel or layout to it now. (Or perhaps I just don't remember) I see a lot of potential for using Google Docs, and as I work with my team members on this project, I am sure I will get ideas for using this in my classroom. The only problem I can see is the email issue. I am not sure if my county will let me ask all my students to sign up for a gmail account. So far, we have just done a little discussion in our group but I look forward to checking out some more of the options. I think it is cool that people can be working on the documents simultaneously.
